Alumina Market Faces Supply Challenges: What’s Next for 2025?

Aluminium

As alumina prices soared to record highs in late 2024, global markets are bracing for more supply disruptions in the coming year. Alumina, the key raw material for aluminium production, faced significant supply shortages due to a combination of environmental regulations, production stoppages, and logistical challenges across major supplying countries. While new projects are expected to alleviate the pressure in 2025, the alumina market remains vulnerable to supply shocks that could impact aluminium prices in the near future.

Supply Disruptions Drive Alumina Prices to Record Levels

Alumina prices surged by over 70% in 2024, with prices peaking above $780 per ton in both China and Australia by November. This price spike was driven by multiple disruptions across the globe, including lower exports from Australia, logistical bottlenecks in Brazil, and production suspensions in Guinea.

In Australia, the tightening of environmental regulations and a fire-related disruption in Queensland affected alumina production, leading to force majeure declarations from major suppliers like Rio Tinto. Meanwhile, in Brazil, Alcoa also declared force majeure in November due to the closure of the Santarem harbor, which blocked access to one of the country’s main bauxite export terminals.

In Guinea, seasonal rains and infrastructure issues led to a nearly 40% reduction in bauxite shipments. Despite these challenges, Emirates Global Aluminium (EGA) indicated that the suspension would not immediately impact its operations, although concerns about long-term supply remained.

Demand and Supply Outlook for 2025

The global aluminium production continued to rise in 2024, particularly in China, where new production capacities came online. Despite this, China’s alumina production has failed to keep pace with aluminium output, leading to a sharp rise in alumina imports. By the end of September, China had imported over 123 million tons of alumina, a 33% increase compared to the same period in 2023.

However, relief may be on the horizon. In 2025, China is set to add more than 13 million tons of new alumina capacity, while other key players, including India’s Vedanta Resources and Guinea’s EGA, are planning significant new alumina refining projects that could ease the global supply squeeze by 2026. UBS forecasts a surplus of 960,000 tons of alumina in China next year, a dramatic turnaround from the deficit observed in 2024.

Despite these optimistic forecasts, challenges remain. The tightness in bauxite supply—especially from Guinea, which supplies 72% of China’s alumina imports—could continue to limit alumina production in China. Environmental regulations in China’s key bauxite-producing provinces, coupled with logistical issues in Guinea, mean that alumina markets will likely remain susceptible to disruptions throughout 2025.

Conclusion

While new alumina production capacities are expected to ease supply pressures in the coming years, the market remains highly vulnerable to supply shocks. Stakeholders in the alumina and aluminium industries will need to closely monitor the situation in major producing regions, particularly in Guinea and China, as these could have significant implications for aluminium prices in 2025. With alumina supply still concentrated in a few key regions, the risk of further disruptions remains high, and the industry must prepare for potential volatility.

Chalco Aluminium Output Rose in 2025 as Primary Metal Prices Supported Revenue

Chalco Aluminium

Chalco aluminium output increased in 2025 as the Chinese state-owned producer raised both primary aluminium and alumina production. The company’s primary aluminium output, including aluminium alloy, rose by 6.2% on the year to 8.08mn t.

Primary aluminium sales also increased by 6.2% to 8.07mn t, showing that Chalco was able to convert higher output into stronger market deliveries. The result reflected China’s stable aluminium demand base and firmer metal prices during the year.

Chalco aluminium output growth came as China’s primary aluminium capacity approached Beijing’s 45mn t ceiling. The company said national capacity reached 44.83mn t by the end of 2025, leaving limited room for further domestic expansion.

Alumina Growth Faced Price Pressure From New Capacity

Chalco produced 17.35mn t of metallurgical alumina in 2025, up 2.9% from the previous year. Metallurgical alumina remains the key feedstock for primary aluminium production, making its pricing central to smelter economics.

The company’s fine alumina output also rose by 4.6% to 4.51mn t. However, metallurgical alumina sales increased by only 1.1% to 6.42mn t, reflecting weaker market conditions in the alumina segment.

China’s alumina capacity expanded sharply by 10.3mn t in 2025, while output rose by 8.3%. But aluminium demand growth was constrained by the national capacity cap, creating a mismatch between alumina supply growth and smelter demand.

As a result, alumina prices fell sharply and Chalco’s alumina revenue dropped by 16.8% from a year earlier. This shows how quickly upstream feedstock profitability can weaken when capacity expands faster than downstream demand.

Aluminium Prices Remained Stronger Despite Capacity Limits

Chalco aluminium output benefited from firmer aluminium prices in 2025. The company said aluminium prices increased alongside gold and copper, supporting a 6.8% year-on-year rise in aluminium revenue.

This contrast between alumina and aluminium is important. Alumina faced surplus pressure, while primary aluminium remained better supported by capacity discipline, geopolitical risks and demand from transportation and power electronics.

Chalco expects China’s domestic alumina market to remain in surplus as new domestic and overseas capacity continues to come online. At the same time, it expects aluminium prices to stay relatively high but more volatile.

The outlook reflects a structural divide in China’s aluminium chain. Alumina producers face oversupply risk, while smelters benefit from a tighter national capacity ceiling and stronger downstream demand.

The Metalnomist Commentary

Chalco’s 2025 results show that China’s aluminium value chain is no longer moving in one direction. Alumina is entering a surplus cycle, while primary aluminium remains supported by capacity limits and industrial demand. That split will shape margins across Chinese aluminium producers in 2026.

Ma'aden aluminium earnings rise on stronger alumina and FRP sales

Ma'aden aluminium

Ma'aden aluminium earnings improved in the third quarter as higher alumina sales volumes outweighed weaker benchmark prices. The Ma'aden aluminium earnings uplift came mainly from alumina and flat-rolled products, even with softer alumina pricing. As a result, Ma'aden aluminium earnings underline the resilience of Saudi downstream metals against a volatile global market.

Alumina sales volumes drive EBITDA growth

Ma'aden reported third-quarter aluminium segment EBITDA of SR755mn, up 16.7pc year on year on solid revenue growth. Sales rose 12.5pc to SR2.8bn, helped by a sharp increase in third-party alumina sales volumes. Alumina production was broadly steady at 486,000t, just 2,000t lower than a year earlier.

However, alumina sales volumes jumped 141pc to 135,000t, signalling a deliberate shift toward monetising surplus material. Alumina prices averaged $385/t in the quarter, down 14.6pc year on year, which capped margin upside. Even so, higher volumes and integrated smelting helped protect profitability along the value chain.

For the first nine months, alumina output held near 1.43mn t, while alumina sales rose 25pc to 266,000t. Prices averaged $431/t, up 5pc, supporting cumulative EBITDA, which still rose 3pc despite a weaker second quarter.

Flat-rolled products underpin premium pricing strategy

Refined aluminium output was flat at 246,000t in the third quarter, highlighting stable smelter operations. Primary aluminium sales volumes increased 4pc to 156,000t, even as average prices dipped 1.1pc to $2,734/t. Over nine months, aluminium output edged up 1pc to 741,000t, while sales slipped 4pc to 435,000t, reflecting some inventory and mix effects.

Flat-rolled product (FRP) performance continued to strengthen Ma'aden aluminium earnings through premium pricing. FRP output reached 76,000t in the quarter, only slightly above last year, but nine-month production climbed 20pc to 231,000t. FRP sales rose to 75,000t in the third quarter and 226,000t year to date, up 15pc. Average FRP prices increased 5.6pc in the quarter to $3,435/t, and 8pc to $3,677/t over nine months.

Therefore, the growing FRP share supports margin resilience versus pure primary metal exposure. Ma'aden has kept full-year production guidance unchanged, signalling operational confidence across alumina, smelting and downstream rolling. This integrated model positions the company well as regional demand for automotive, packaging and industrial aluminium continues to expand.

The Metalnomist Commentary

Ma'aden’s third-quarter numbers confirm that value-added products now anchor profitability more than headline aluminium prices. The combination of integrated alumina, primary metal and FRP capacity provides a structural buffer against market volatility. Investors should watch how Ma'aden balances export volumes, domestic demand and future FRP upgrades as GCC industrialisation accelerates.

Hydro 4Q 2025 Earnings Fall as Alumina Weakness Offsets Aluminum Strength

Hydro

Hydro 4Q 2025 earnings fell sharply in the quarter as weaker alumina prices and currency effects hit profitability. The Norwegian producer reported quarterly Ebitda of NKr5.59bn, down 27.5pc from a year earlier. Lower realized alumina prices and a stronger Norwegian krone drove much of the decline. As a result, Hydro 4Q 2025 earnings showed how uneven the aluminum value chain remains.

The contrast inside the portfolio was clear. Hydro’s alumina business weakened significantly, while its aluminum metal segment delivered strong gains. Lower raw material costs and firmer aluminum prices supported primary metal earnings. However, weak downstream demand and poorer trading results offset much of that benefit. Therefore, Hydro 4Q 2025 earnings reflected strong upstream metal pricing but softer performance elsewhere.

Full-year performance looked more resilient than the quarter alone suggests. Hydro’s full-year Ebitda reached NKr28.9bn, up 9.87pc from 2024. That shows the company still benefited from stronger aluminum market conditions across the year. Meanwhile, the fourth quarter exposed growing pressure in alumina and downstream operations.

Hydro Alumina Business and Metal Markets Moved in Opposite Directions

Hydro alumina business was the weakest part of the quarter. Ebitda in bauxite and alumina fell 72pc year on year to NKr1.39bn. Lower alumina prices and a stronger Brazilian real weighed heavily on results. Rising Indonesian refining output and Chinese oversupply also pressured alumina pricing. Consequently, Hydro alumina business became the main drag on quarterly earnings.

The aluminum metal division told a different story. That segment posted Ebitda of NKr3.71bn, up 90.2pc from a year earlier. Lower alumina costs and higher all-in aluminum prices drove the improvement. LME three-month aluminum averaged $2,847/t in the quarter, above the prior-year level. As a result, aluminum metal earnings helped cushion weaker results elsewhere.

Metal markets were much less supportive. The division posted a negative Ebitda of NKr56mn, compared with a positive NKr318mn a year earlier. Lower sourcing and trading performance, negative inventory valuation, and currency effects all hurt results. However, recycling operations provided some partial support.

European Extrusion Demand Remains Soft Despite Restructuring Efforts

European extrusion demand remained weak and margins stayed under pressure. Hydro’s extrusion division reported a negative Ebitda of NKr62mn, down from positive earnings of NKr319mn a year earlier. Lower sales margins and lower volumes drove the decline. Therefore, downstream demand remains a serious concern for Hydro.

Demand trends offered only limited comfort. European extrusion demand was flat year on year, though it rose 3pc from the previous quarter. US demand was also flat year on year, but fell 8pc quarter on quarter. That suggests end markets are still not delivering a strong recovery. Consequently, Hydro continues facing a slow and fragile downstream environment.

The company is responding with restructuring. Hydro said it will close five extrusion plants in Europe this year. It also completed a strategic workforce reduction, with around 850 employees having left or expected to leave by the first half of 2026. As a result, Hydro is trying to protect long-term competitiveness while market conditions stay difficult.

The Metalnomist Commentary

Hydro’s quarter shows that strong aluminum prices alone cannot carry the full business when alumina and downstream segments weaken. The company still benefits from primary metal strength, but its earnings mix is becoming more dependent on that support. If downstream demand stays soft, restructuring and cost control will matter as much as market pricing in 2026.

Nanshan Indonesia alumina capacity reaches 4mn t/yr as Indonesia alumina expansion accelerates

Nanshan Aluminium

Nanshan Indonesia alumina capacity reached a new milestone after the company launched phase two in Indonesia. Nanshan Indonesia alumina capacity now totals 4mn t/yr across the group after adding 1mn t/yr. As a result, Indonesia alumina expansion continues to reshape regional refining supply.

Nanshan’s Indonesian subsidiary, PT Bintan Alumina Indonesia, now holds 2mn t/yr of alumina capacity. The first 1mn t/yr unit began operating in the third quarter this year. Meanwhile, the phase-two start strengthens Nanshan’s feedstock security for the wider aluminium value chain.

Why Indonesia alumina expansion is now a strategic supply move

Indonesia alumina expansion gives Chinese producers a route around domestic capacity limits. China maintains a 45mn t ceiling for aluminium capacity. Therefore, producers increasingly place upstream assets offshore to lock in bauxite and refining capacity.

Nanshan also built a modern port to improve export logistics and reduce bottlenecks. The port supports larger-scale loading and more predictable shipping cycles. As a result, Nanshan Indonesia alumina capacity can translate into more stable deliveries for customers.

Cost advantages deepen as energy and raw materials align locally

Local bauxite and coal availability supports a lower-cost alumina platform in Indonesia. Nanshan also pointed to a stable energy supply system at the site. Meanwhile, integrated infrastructure can reduce unit costs and improve operating resilience.

Chinese aluminium investment Indonesia has expanded as companies pursue supply security and policy alignment. China and Indonesia also agreed to deepen cooperation in critical minerals and renewable energy. Therefore, more projects may follow as investors seek long-term refining optionality.

The Metalnomist Commentary

Nanshan’s scale-up strengthens Southeast Asia’s role in the global alumina supply chain. However, competitiveness will hinge on energy pricing and permitting stability. The winners will integrate logistics, power, and bauxite into one controllable system.

Atalco to boost US alumina, gallium production

Atalco

Atalco to boost US alumina, gallium production after securing $450mn to restart capacity and add new critical minerals output. Atalco to boost US alumina, gallium production by restoring its Louisiana refinery to nameplate levels and installing a new primary gallium circuit. As a result, Atalco to boost US alumina, gallium production as Washington pushes harder for resilient domestic supply chains.

Atlantic Alumina will direct the funding to its Gramercy, Louisiana, refining site to return alumina production to 1.2mn t/yr. The company will also build a 50 t/yr gallium production circuit and upgrade mineral processing and power generation capability. Meanwhile, the company has not provided a public project timeline or detailed restoration plan.

Why alumina and gallium now sit in the same national security basket

Atalco to boost US alumina, gallium production because both materials matter for defense, aerospace, and semiconductors. The US has limited domestic alumina output relative to demand and no primary gallium production, which creates exposure during trade disruptions. Therefore, a restart at Gramercy could strengthen supply assurance for downstream aluminium and high-tech manufacturing.

Atalco operates the only US alumina refinery, which makes the site strategically important. The refinery processes bauxite, and gallium can be recovered as a by-product stream in alumina production. However, recovery performance and unit economics will depend on bauxite chemistry, circuit design, and sustained operating rates.

Funding structure and supply chain linkages signal a broader buildout

Atalco to boost US alumina, gallium production with a blended finance structure that mixes public and private capital. The Department of Defense is providing $150mn through an industrial base program, while the remaining $300mn comes from a private capital sponsor linked to Concord Resources. As a result, the project reflects a growing model where government anchors projects that private markets might otherwise delay.

Feedstock sourcing also matters for delivery certainty. Atalco receives bauxite from Jamaica through a joint venture, which supports continuity of supply while the US rebuilds midstream capacity. Meanwhile, parallel Louisiana efforts to recover gallium from red mud highlight a wider push to extract critical minerals from industrial waste streams, not just primary mines.

The Metalnomist Commentary

This project is a strategic restart with a dual benefit: aluminium supply resilience and new domestic gallium output. However, the market will judge success on execution speed and reliable gallium recoveries at scale. If Gramercy stabilizes operations, it could become a template for midstream critical minerals re-industrialization.

Alcoa Western Australia Alumina Output Cut After Cyclone Narelle Gas Disruption

Alcoa Western Australia

Alcoa Western Australia alumina production was reduced after Cyclone Narelle disrupted domestic gas supply to the company’s Pinjarra and Wagerup refineries. The US aluminium producer temporarily lowered process flow rates at both facilities because of gas supply constraints in Western Australia.

The disruption followed Cyclone Narelle’s impact on key offshore and onshore gas infrastructure. Western Australia’s LNG and domestic gas systems faced interruptions after the cyclone passed over major production facilities.

Alcoa Western Australia alumina operations are important to the global aluminium value chain because alumina is the essential feedstock for primary aluminium smelting. Any sustained refinery disruption could affect alumina availability, regional pricing, and downstream aluminium supply planning.

Gas Supply Disruption Hits Alumina Refining Operations

Alumina refining depends heavily on reliable energy supply. Refineries require heat and process energy to convert bauxite into alumina, making gas availability a direct operational risk in Western Australia.

Alcoa said it had temporarily reduced process flow rates at Pinjarra and Wagerup, but it did not provide a timeline for returning to normal operations. That uncertainty will keep buyers and traders focused on the duration of the gas disruption.

Woodside Energy reported an interruption at the Karratha Gas Plant on 27 March. Chevron also took the Wheatstone facility offline on 26 March and said it would take weeks to return to full production after cyclone damage.

Weather Risk Adds Pressure to Aluminium Raw Material Supply

Alcoa Western Australia alumina output cuts show how weather events can quickly affect the aluminium supply chain. The issue is not bauxite availability, but the energy infrastructure needed to keep refining assets running.

Western Australia is a major alumina-producing region, and refinery curtailments can influence sentiment in the broader raw material market. If gas supply remains constrained, buyers may reassess short-term alumina availability and logistics risk.

The disruption also reinforces the importance of energy resilience for metals processing. As extreme weather affects ports, gas plants, power systems, and industrial sites, producers will need stronger contingency planning for critical inputs.

The Metalnomist Commentary

Alcoa’s refinery cuts show that alumina supply risk can emerge from energy infrastructure, not only mining or refinery equipment. For aluminium producers, secure and resilient power and gas supply is becoming a core competitiveness factor.

China’s IMDTECL Launches $1bn Alumina Plant Project in Guinea

China Alumina

New alumina facility marks China’s deepening investment in bauxite-rich West Africa

IMDTECL Begins Construction of 1.2mn t/yr Alumina Plant

China’s Inner Mongolia Dian Tou Energy (IMDTECL) began building a $1 billion alumina plant in Tougnifilidy, Guinea, on 26 March 2025. The integrated facility will produce 1.2 million tonnes per year of alumina and include bauxite mining and associated infrastructure.

This development reinforces China’s strategic grip on Guinea’s bauxite reserves, which are vital for the global aluminum supply chain. The new plant aligns with Guinea’s national requirement that major miners invest in in-country refining capacity to enhance local value addition.

Guinea Rises as a Strategic Alumina Hub

Guinea remains China’s largest bauxite supplier, with shipments hitting 110 million tonnes in 2024, up 12% year-on-year. This accounted for nearly 70% of China’s total bauxite imports, underscoring the West African country’s importance in the aluminum value chain.

In response to this dependency, Guinean regulators are enforcing stricter policies, including mandating domestic alumina processing. These measures are designed to capture more downstream value and stimulate industrial development in Guinea.

Outlook: Strong Growth in West African Alumina Capacity

Market analysts expect a significant rise in Guinea’s alumina production over the next five years due to multiple plant investments. As a result, China’s reliance on raw ore imports could be partly replaced by alumina shipments, easing pressure on domestic refiners.

Meanwhile, projects like IMDTECL’s could redefine global bauxite trade flows, encouraging other nations to localize resource processing. The IMDTECL project may also influence global alumina prices and trade logistics, especially within the China–Africa supply corridor.

The Metalnomist Commentary

China's vertical integration in Guinea reflects a new era of resource diplomacy and industrial policy enforcement. As refining moves closer to the mine, emerging economies like Guinea could gain more influence over global metals markets.

Chalco Reports Increased Aluminium and Alumina Output in January-September

Chalco

Chalco, China's state-owned aluminium producer, has reported notable increases in both its primary aluminium and alumina production for the January-September period, compared to the same period last year. The rise in output is reflective of strong domestic demand for these materials, which have supported price growth across the industry.

During the first nine months of 2024, Chalco’s primary aluminium output, including aluminium alloys, rose by 14% year-on-year, reaching 5.62 million tons (mn t). This increase in production aligns with a 13% rise in primary aluminium sales, which also reached 5.6 million tons over the same period. This performance underscores Chalco's strong market position in the aluminium sector, with solid sales and production figures helping to bolster its standing in an increasingly competitive market.

Chalco also saw a slight increase in its metallurgical alumina output, a crucial feedstock used in primary aluminium production. The company produced 12.57 million tons of alumina in January-September, marking a 0.9% rise over the previous year. However, the company reported a decline in alumina sales, which fell by 4.8% to 4.77 million tons during the same period.

In terms of product segmentation, Chalco’s fine alumina production grew by 15% year-on-year, reaching 3.25 million tons, up from 5.01 million tons in 2023. Fine alumina is used in the production of higher-value products, and this increase reflects Chalco's shift towards higher-quality, more profitable outputs.

The increase in both aluminium and alumina production was supported by strong domestic demand, which helped push prices higher during the reporting period. Chalco noted that higher profitability within the aluminium and alumina production sectors encouraged manufacturers to maximize their production run rates, further driving output.

According to China's National Bureau of Statistics, the country’s total aluminium production grew by 4.6% year-on-year to 32.56 million tons in the January-September period, while alumina output rose by 2.4% to 63.13 million tons.

Strong Demand Supports Price Growth in Aluminium and Alumina

The performance of Chalco and other domestic producers is being driven by persistent domestic demand in China, one of the world’s largest consumers of both aluminium and alumina. Rising prices for both materials have contributed to improved profitability across the industry. Despite a decline in alumina sales, Chalco’s overall production and sales growth in aluminium highlights a promising outlook for the company in the remainder of the year.

As Chalco continues to ramp up production, it is expected that the market will remain focused on the ongoing balance between domestic demand, production capabilities, and price fluctuations, particularly as global economic conditions continue to evolve.

Norsk Hydro Reports Alumina Output Decline, but Strong Earnings in Third Quarter of 2024

Norsk Hydro

Alumina Production Declines, Sales Surge

Norwegian aluminum producer Norsk Hydro has released its third-quarter results for 2024, revealing a drop in alumina production but an increase in alumina sales. Despite producing only 1.46 million metric tonnes of alumina in the third quarter, down from 1.52 million tonnes the previous year, Hydro sold 2.7 million tonnes of alumina, an increase of 508,000 tonnes from the same period in 2023. To make up for the shortfall in production, Hydro sourced an additional 555,000 tonnes of alumina.

Strong Performance in Other Production Segments

While alumina production declined, other production segments remained stable. Primary aluminum production saw only a minor decrease of 1,000 tonnes, totaling 511,000 tonnes. Hydro's aluminum metal segment sold 71% of its expected primary aluminum production for the fourth quarter of 2024, at an average London Metal Exchange (LME) price of $2,445 per tonne, slightly below the current LME settlement of $2,600 per tonne.

In addition, Hydro experienced a decline in extrusion sales volumes, which dropped by 20,000 tonnes to 240,000 tonnes. Despite this, demand for extrusion products is expected to rebound in 2025, as the Federal Reserve is anticipated to lower interest rates. Recycling production also saw a decline of 6,000 tonnes, reaching 170,000 tonnes for the quarter.

Significant Increase in Alumina Earnings

Hydro's bauxite and alumina sector reported a remarkable increase in earnings before financial items, tax, depreciation, and amortization (EBITDA), reaching 3.5 billion Norwegian Krone ($318 million). This impressive performance was primarily driven by the rise in the realized alumina price from $349 per tonne to $494 per tonne. Additionally, lower raw material costs and favorable currency effects contributed to the substantial 25-fold increase in EBITDA compared to the same period in 2023.

Robust Overall Profit for the Quarter

Norsk Hydro reported a strong overall profit of 3.506 billion NKr for the third quarter of 2024, marking a significant increase from the 345 million NKr profit in Q3 2023. This surge in profitability reflects Hydro's ability to capitalize on rising alumina prices and its strategic management across various production sectors.

China's Alumina Capacity Expansions to Slow Down Under New Policy

China Alumina

Government Plan Signals Shift in Alumina Market Strategy

China's alumina capacity growth is set to decelerate following a new industrial development plan released in March 2025. The Aluminium Industry High-Quality Development Action Plan (2025–2027) requires new alumina projects to include bauxite mining operations and avoid high-pollution zones.

This move aims to control overheated investments, reduce redundant competition, and enhance domestic resource utilization, according to speakers at a recent CNIA conference. Market participants believe this policy shift will suppress further rapid expansions, especially amid growing signs of alumina oversupply.

Oversupply Risks and Price Volatility Emerging in 2025

China became a net alumina exporter in 2024, with exports rising by 43pc, driven by tight overseas supply and rising global prices. Domestic alumina prices surged to a record Yn5,800/t ($793.49/t) in December, but have since plummeted below Yn4,000/t, leading to negative profit margins.

In the first two months of 2025, output rose 13pc year-on-year to 15.13mn t, as new projects in Guangxi and Shandong added 3mn t/yr of capacity. Industry estimates now forecast a 10mn t/yr rise in total capacity for the year, while aluminium output is expected to grow only 1.2pc, creating a projected 1.3mn t surplus.

CNIA expects alumina production to hit 91mn t in 2025, with exports at 1.5mn t and consumption reaching 88.2mn t. This imbalance highlights the risk of prolonged low prices and margin compression in the sector.

China to Boost Domestic Bauxite and Recycling Capabilities

To support its alumina sector, China plans to expand domestic bauxite resources by 3–5pc by 2027. This includes exploration of coal-bed bauxite and development of low-grade, high-sulphur reserves, traditionally seen as challenging due to environmental concerns.

Shanxi province is likely to be a key site for new bauxite mining under coal beds, as noted by CNIA expert Meng Jie. In 2024, domestic bauxite output dropped 12pc to 73.9mn t, while imports rose 13pc to 159mn t, making up 68pc of total supply.

China will also promote aluminium recycling, aiming to produce 15mn t of secondary aluminium by 2027. This includes industry park development and relaxed import rules for aluminium scrap, supporting the transition to a circular economy in aluminium production.

The Metalnomist Commentary

China’s new alumina policy marks a clear pivot toward sustainability, supply security, and rational investment. While the action plan may cause short-term market disruption, it paves the way for a more integrated and resilient aluminium value chain—anchored in controlled expansion, domestic bauxite development, and circular material flows.

China Gallium Production Expands as Jiayuan Prepares Shandong Trial Plant

Jiayuan New Material

China gallium production is set to expand again as Binzhou Jiayuan New Material prepares to put its 30 t/yr gallium plant in Shandong province into trial operation at the end of April. The facility marks the first phase of a two-stage project designed for total capacity of 60 t/yr.

The new plant is located in Lingang Industry Park in the Zhanhua zone of Binzhou city. Domestic producer Zhuhai Fangyuan holds a 24% stake in Jiayuan, giving the project a link to China’s established gallium production base.

China gallium production has become more strategically important since Beijing introduced strict dual-use export controls on the metal in August 2023. Gallium is a critical feedstock for compound semiconductors, power electronics, radio-frequency devices, optoelectronics and other advanced technologies.

Alumina Integration Strengthens Jiayuan’s Feedstock Position

Jiayuan’s feedstock will come from nearby Binzhou Huihong New Material, a subsidiary of major Chinese alumina producer Shandong Weiqiao. Huihong is located in the same industrial park, giving the gallium project a close raw material supply base.

This matters because gallium is typically recovered as a by-product of alumina production. Alumina refineries can extract gallium from process streams, making alumina scale, process control and recovery technology central to gallium supply growth.

Huihong plans to gradually raise alumina output to 8mn t/yr from the current 4mn t/yr. Gallium production is expected to increase to 120 t/yr accordingly, creating a larger integrated alumina-gallium platform in Shandong.

The project therefore shows how China gallium production is increasingly tied to major alumina producers. Companies with large alumina capacity can add gallium recovery as a higher-value by-product route, especially when prices and strategic demand justify investment.

Export Controls and Semiconductor Demand Drive Capacity Additions

Chinese alumina producers have accelerated gallium capacity investment in recent years after prices surged in 2022. Demand from domestic high-tech sectors and the metal’s strategic role in semiconductor manufacturing have raised the value of integrated gallium recovery.

China’s export controls have further increased the importance of domestic capacity. Gallium is used in gallium arsenide and gallium nitride materials, which support semiconductors, LEDs, lasers, satellite communications, radar systems, chargers and power devices.

Several new Chinese production lines have recently entered the market. Facilities with combined capacity of 140 t/yr came on stream in Guizhou province in the fourth quarter of 2024.

Additional capacity followed in 2025. Vital launched an 80 t/yr facility in Chongqing in the second quarter, while Luoyang Heungkong Wanji started its 60 t/yr smelter and ramped output close to full capacity by September.

More projects are under development. Guizhou Qiya began construction of a 20 t/yr third-phase project in Kaili in September 2025, while Guangxi Xinfa received approval in November 2025 for a 100 t/yr project in Jingxi.

These projects show that China gallium production is expanding across several provinces. However, export licensing still gives Beijing significant control over how much material reaches overseas buyers.

The Metalnomist Commentary

Jiayuan’s Shandong plant reinforces China’s ability to turn alumina scale into strategic gallium supply. For global semiconductor and defense supply chains, the key issue is not only how much gallium China can produce, but how much it will allow to leave the country.

South32 alumina output increase set for FY2026–27 on Worsley expansion

South32

South32 alumina output increase is planned as the miner lifts FY2026–27 production to 5.3mn t. The South32 alumina output increase reflects new, higher-quality bauxite areas approved in Western Australia. As a result, the South32 alumina output increase contrasts with a decline in primary aluminium smelting.

Worsley Alumina lifts throughput as new bauxite areas come online

South32 will raise alumina production to 5.3mn t in FY2026–27. It guided 5.1mn t for FY2024–25 and FY2025–26. The step-up relies on Worsley Alumina’s mine life extension and better bauxite quality. Moreover, the firm will invest $90mn in 2025–26 to support the expansion. Australian federal approval in February unlocked new mining areas. Therefore, Worsley’s feed blend should improve, stabilizing refinery yields and costs. Higher-grade bauxite typically reduces caustic consumption and energy intensity. Consequently, unit costs and carbon intensity can trend lower as ore quality rises.

Aluminium smelting retreats; Chinese bauxite reliance rises

South32’s aluminium output will fall to 885,000t in FY2026–27. It was 1.2mn t last year and 1.1mn t expected in FY2025–26. The Mozal smelter will produce 240,000t by March 2026, then enter care and maintenance. Power constraints drive the pause, curbing ex-China metal supply. However, South32 sees long-term aluminium growth outside China. It expects non-Chinese producers to deliver 90pc of new capacity over the next decade. Meanwhile, China’s refineries will lean more on imported bauxite. South32 projects imports will support 79pc of Chinese alumina output by 2029. That compares with 71pc in 2024, underscoring rising seaborne dependency. As a result, bauxite trade flows and refinery siting remain strategic for decarbonized metals.

The Metalnomist Commentary

The alumina uplift at Worsley offsets smelting headwinds and preserves South32’s oxide leverage. Watch unit costs, energy inputs and caustic usage as higher-grade bauxite feeds the circuit. Policy and power reliability will dictate how quickly mothballed smelting capacity can return.

Alcoa Maintains 2024 Guidance as Third-Quarter Production and Revenue Climb

Alcoa

Alcoa Corporation, a leading U.S.-based integrated aluminum producer, upheld its 2024 production guidance for alumina and aluminum despite achieving increased quarterly production and revenue in Q3. The company continues to project aluminum production at 2.2-2.3 million metric tonnes (t) and alumina output at 9.8-10 million t, unchanged from prior estimates.

Third-Quarter Highlights

Aluminum production grew 5% year-over-year, reaching 559,000 t in Q3 2024 compared to 532,000 t in the same period last year. Aluminum shipments also rose slightly to 638,000 t from 630,000 t. Meanwhile, bauxite production declined to 9.4 million dry metric tonnes (dmt) from 10.7 million dmt a year ago. Alumina output decreased to 2.435 million t, down from 2.805 million t, with shipments falling to 2.052 million t.

Revenue and Market Dynamics

Alcoa’s Q3 revenue rose nearly 12% year-over-year to $2.9 billion, driven by higher alumina prices, which averaged $485/t compared to $354/t in Q3 2023. Aluminum prices also increased to $2,877/t, up from $2,647/t a year earlier. Third-party aluminum sales rose approximately 10% to $1.8 billion. Improved alumina pricing and lower raw material costs helped narrow segment losses to $11 million from $15 million in the same period last year.

The company posted $90 million in profits, a significant improvement from the $168 million loss reported in Q3 2023.

Strategic Developments

Alcoa raised its annual shipment forecast by 200,000 t to 12.9-13.1 million t, reflecting increased trading volumes. However, a wider spread between production and shipments emerged due to external sourcing of alumina amid the ongoing curtailment of the Kwinana refinery in Australia.

Alcoa is advancing a strategic partnership with IGNIS, a Spanish renewable energy investment firm. The agreement includes selling 25% of Alcoa's operations in Spain and a potential €175 million ($189 million) investment by Alcoa if required. The deal is contingent on government and employee support.

On 15 October, Alcoa signed a long-term supply agreement with Aluminum Bahrain (Alba) to deliver 1.5 million t of smelter-grade alumina over 10 years beginning in 2026, bolstering its position as a global alumina supplier.

Outlook

With strong alumina prices and strategic partnerships, Alcoa expects its alumina segment performance to improve by $30 million, driven by increased shipments and reduced production costs. As global aluminum demand remains steady, Alcoa’s ability to adapt through cost efficiency and partnerships positions it favorably for future growth.

Metlen and Rio Tinto Sign Strategic Bauxite and Alumina Supply Deal

Metlen

Long-Term Agreement Strengthens Supply Chains and Expands Alumina Trade

Metlen Targets Alumina Growth with €295.5mn Investment in Greece

Greek aluminium and energy conglomerate Metlen, formerly known as Mytilineos, has signed a long-term supply agreement with Rio Tinto, the Anglo-Australian mining giant. The deal ensures mutual access to critical raw materials, reinforcing both firms' strategic positions in the aluminium value chain.

Rio Tinto to Deliver Bauxite from Guinea Starting 2027

Under the agreement, Rio Tinto will supply Metlen with 14.9 million tonnes of bauxite over 11 years, sourced from the CBG mine in Guinea. This move secures a steady bauxite flow for Metlen, aligning with its downstream processing plans. Simultaneously, Metlen will provide Rio Tinto with 3.9 million tonnes of alumina across eight years, with a potential three-year extension.

Both supply streams are scheduled to begin in 2027, positioning both companies for long-term operational synergy.

Greek Expansion to Boost Alumina Capacity by 400,000t/yr

Metlen also confirmed a €295.5 million investment to expand its alumina production at Agios Nikolaos, Greece. This will add 400,000 tonnes/year to its current capacity of 865,000 tonnes, solidifying Metlen’s presence in the global alumina market.

The investment package includes upgrades to energy and transport infrastructure and new gallium production facilities. These developments will bolster Metlen's vertical integration and export potential, particularly as global alumina demand rises.

Record Financials Back Strategic Growth Plan

In 2024, Metlen achieved a record EBITDA of €1.08 billion, up 7% year-over-year. Although net profits dipped slightly to €615 million, the metals division surged, posting €297 million in EBITDA, driven by a 46% rise in alumina prices and a 7% increase in aluminium prices.

While the energy segment saw a 1.7% decline in EBITDA to €753 million, the overall performance reinforces Metlen’s financial strength ahead of its expansion and supply commitments with Rio Tinto.

The company stated the deal will deliver dual benefits: securing upstream bauxite supply and maximizing profit through expanded alumina exports under competitive global terms.

Alba and Alcoa Renew Alumina Supply Agreement Amid Tightening Global Market

Aluminium Bahrain(Alba)

Aluminium Bahrain (Alba), a leading aluminium producer in the Middle East, has renewed its alumina supply agreement with the U.S.-based integrated aluminium company Alcoa. This new, extended agreement will secure up to 16.5 million tonnes of smelter-grade alumina over the next decade, beginning in 2026. This strategic partnership not only strengthens Alba’s operational resilience by ensuring a steady alumina supply but also bolsters its competitive stance in the global aluminium market.

In a recent statement, Alba CEO Ali al-Baqali remarked, “This agreement not only guarantees a steady supply of alumina for our operations but also reinforces our position as a key player in the global aluminium market.”

The renewal of Alba’s alumina supply agreement comes at a critical time as the alumina market faces tightening supply. This is largely due to recent output disruptions in China, a significant alumina-producing nation, which has put pressure on the supply chain. Additionally, Alcoa recently announced plans to fully suspend production at its 2.2 million tonne-per-year Kwinana refinery in Australia by the end of this year, further impacting global supply.

Adding to the challenges, Guinea recently paused bauxite shipments from the subsidiary of UAE-based Emirates Global Aluminium. Although initially this is not expected to directly impact production at Al Taweelah, Emirates Global’s alumina refinery in the UAE, such disruptions in Guinea, a major bauxite source, signal potential long-term effects on the alumina and aluminium industries worldwide.

Rio Tinto 2026 production guidance signals steady aluminium and higher alumina

Rio Tinto

Rio Tinto 2026 production guidance sets 2026 targets for bauxite, alumina, and aluminium. Rio Tinto 2026 production guidance keeps aluminium steady while it lifts alumina output. The company targets 58–61mn t of bauxite, 7.6–8mn t of alumina, and 3.25–3.45mn t of aluminium. However, tailings limits and power contracts shape the real supply outlook.

Bauxite and alumina tighten around operational constraints

Bauxite volumes will dip slightly as Rio Tinto eases Weipa output after a strong 2025. The company ran the Amrun mine above capacity for most of 2025. As a result, the complex lifted production by 8pc in January–September. Meanwhile, Rio Tinto plans a 2027 expansion at Norman Creek.

Alumina guidance rises, but Rio Tinto will curb output at Yarwun refinery in late 2026. The company expects 7.6–8mn t of alumina in 2026. However, it will cut the 3mn t/yr refinery by 1.2mn t/yr from October 2026. The site supplied about 39pc of Rio Tinto’s alumina in July–September.

Aluminium stays steady as capex and power risks grow

Aluminium output stays flat, yet the company invests heavily in low-carbon capacity. Rio Tinto plans 3.25–3.45mn t of aluminium in 2026. Meanwhile, it will expand the AP60 smelter in Canada to 220,000 t/yr. The $1.1bn project will add 96 pots in early 2026.

Australian power risk now threatens stable smelting volumes. Rio Tinto must secure a new power deal with Hydro Tasmania for Bell Bay smelter by end-2026. However, high energy costs could also force a 2028 closure decision at Tomago smelter in New South Wales. Meanwhile, Rio Tinto pursues growth through an India low-carbon smelter plan with AMG Metal and Mining. Therefore, Rio Tinto 2026 production guidance will face execution risk beyond the headline ranges.

The Metalnomist Commentary

Rio Tinto’s stable aluminium guidance hides rising constraints across refining and smelting. However, the AP60 expansion signals confidence in premium, low-carbon metal demand. Therefore, investors should watch tailings solutions and power negotiations more than volume targets.

Alba alumina refinery MoU signals Egypt upstream push

Alba alumina

Alba alumina refinery MoU positions Bahrain’s smelter for upstream resilience. The Alba alumina refinery MoU outlines a pathway to build an Egyptian refinery. The Alba alumina refinery MoU also targets offtake and potential equity participation to secure feedstock.

Why Alba wants upstream alumina in Egypt

Alba lacks captive alumina while peers have integrated assets. Therefore, alumina price swings hit margins directly. Egypt offers bauxite access via global suppliers and strong logistics to MENA smelters. A refinery in Egypt could diversify supply and reduce freight exposure. Meanwhile, offtake agreements would stabilize volumes and pricing structures.

What the MoU could include next

The MoU frames feasibility, permitting, and financing studies. It also points to long-term offtake agreements with Alba and possible equity stakes. Stakeholder due diligence will assess capex, energy costs, red-mud handling, and ESG compliance. As a result, the project could mirror regional models used by Ma’aden and EGA. Commercial success will hinge on energy tariffs and stable maritime routes.

The Metalnomist Commentary

Alba’s integration move is strategically overdue. If Egypt delivers competitive gas or power tariffs, a coastal refinery with firm offtake could narrow Alba’s cost gap to integrated Gulf rivals. Execution risk centers on permitting cadence, residue management, and multi-currency financing in a volatile rate environment.

Brimstone to Produce US-Sourced Alumina by 2030

Brimstone

Brimstone, a California-based cement manufacturer, has announced plans to produce smelter-grade alumina in the United States by 2030. This initiative will be integrated into the company's decarbonized cement manufacturing process.  Currently, the sole operational alumina refinery in the US relies entirely on imported unrefined alumina.

Reducing Reliance on Imports

Brimstone's innovative approach will produce alumina from carbon-free calcium silicate rocks, reducing the need for both imported alumina and imported bauxite, the raw material typically used in alumina production.  The US relies heavily on imported alumina and bauxite.  From January to September, the US imported 989,000 metric tonnes of alumina, with 749,000 tonnes coming from Brazil.  During the same period, the US also imported 1.6 million tonnes of unrefined bauxite, including 1.3 million tonnes from Jamaica and 232,000 tonnes from Turkey, along with 272,000 tonnes of calcined bauxite.

Project Timeline and Funding

Brimstone will begin pilot operations in 2025 and aims to have its commercial demonstration plant operational by 2030.  The company has received $8.7 million in federal cost-share funding from the Department of Energy's Office of Clean Energy Demonstrations (part of a total $189 million commitment) to support site selection and initial studies.

Nalco Record Profit Highlights India’s Aluminium Market Strength

Nalco

Nalco record profit in FY2025/26 shows how stronger production volumes, higher aluminium prices and improved operating efficiency lifted India’s state-owned aluminium producer to a new earnings high. The company reported profit of 58.16bn rupees for the year to March, up 9.2% from a year earlier.

Nalco record profit was supported by revenue growth of 6.3% to Rs178.43bn. In the final quarter of the financial year, profit rose by 7% to Rs17.18bn, while revenue increased by 7.9% to Rs51.03bn.

Nalco record profit also reflects stronger market realisations. Three-month aluminium prices on the London Metal Exchange averaged $2,780/t through the financial year, up from $2,553/t in the previous year.

The result reinforces the importance of India’s aluminium value chain. Higher domestic metal sales and stable alumina output strengthen Nalco’s position as India expands infrastructure, power, transport, packaging and industrial manufacturing.

Record Aluminium Output Supports Domestic Demand

Nalco set new records for aluminium production and sales during the year. Cast aluminium production reached 472,000t, while aluminium sales totalled 474,000t.

Domestic sales reached a record 461,000t. This is strategically important because it shows that India’s internal aluminium demand remains strong enough to absorb most of Nalco’s output.

Aluminium consumption in India is tied to several structural growth sectors. Power transmission, construction, transport, packaging, electrical products and manufacturing all require more aluminium as industrial activity expands.

Higher domestic sales also reduce exposure to export volatility. For Nalco, a larger Indian customer base can improve sales stability when global trade flows are affected by tariffs, premiums or regional demand swings.

The production record also points to better operating execution. Higher volumes matter only when supported by plant reliability, cost discipline and stable raw material flows.

Nalco said stronger production, improved realisations and operating efficiency across business units drove the performance. That combination allowed the company to capture better market pricing while expanding output.

Alumina and Price Realisations Strengthen Earnings Base

Nalco also produced 2.3mn t of alumina hydrate and recorded 1.4mn t of alumina sales. Alumina remains central to the company’s integrated aluminium model.

Integrated alumina supply gives aluminium producers stronger cost control. It can also protect margins when external alumina markets tighten or when smelters face higher raw material costs.

The increase in LME aluminium prices was another major earnings driver. Higher benchmark prices improved realisations and helped lift profits even as cost pressures remained a risk across energy-intensive metal production.

For India’s aluminium sector, Nalco’s results show the value of scale and integration. Producers with bauxite, alumina and smelting capacity can benefit more directly when aluminium prices rise and domestic demand expands.

The company’s record performance also supports India’s broader industrial policy goals. Aluminium is essential for electrification, infrastructure, transport lightweighting, renewable energy equipment and downstream manufacturing.

Nalco’s challenge now is to sustain output discipline and margin strength if aluminium prices become more volatile. The market remains exposed to energy costs, global trade measures and supply disruptions.

The Metalnomist Commentary

Nalco’s record profit shows that India’s aluminium market is gaining strength from domestic consumption, not only export opportunity. The strategic advantage will belong to producers that combine integrated alumina supply, reliable smelting operations and exposure to India’s expanding industrial base.
