Sinomine to Build Copper, Gallium, and Germanium Smelters in Africa: A Strategic Move for Resource Expansion

Sinomine

Chinese diversified mining company Sinomine Resource has announced a bold step in its global resource strategy by unveiling plans to build a copper smelter at its Kitumba mine in Zambia and a germanium/gallium recycling facility at the Tsumeb smelter in Namibia. These investments come as part of Sinomine's ongoing strategy to expand its reach in the mining sector, focusing on copper, germanium, and gallium—key strategic metals for the global market.

Sinomine’s Copper Smelter in Zambia

The first phase of Sinomine’s expansion involves a $562.9 million investment in a new copper smelter at its Kitumba mine in Zambia. The smelter will process 3.5 million tons per year of copper ore, with a production capacity of 60,000 tons per year of copper cathode. The project is set to be completed by late 2026, with a construction period of 1½ years, and will have an expected operating life of 11 years after commissioning. The smelter’s establishment aligns with Sinomine's strategy of expanding its copper resources globally, particularly in Africa, a continent rich in mineral deposits.

Sinomine took control of the Kitumba mine in March and began production in August, marking a significant milestone in its overseas copper operations. The Kitumba project complements Sinomine’s other Zambian ventures, including the commissioning of a second concentrator at the Kasisi copper and gold mine earlier in 2023. This move has significantly increased copper ore processing capacity, further bolstering Sinomine’s growing presence in Zambia.

Expansion in Namibia: Gallium and Germanium Recycling Facility

In addition to copper, Sinomine has also turned its attention to germanium and gallium, two metals that are crucial to industries such as information technology, renewable energy, and aviation. The company is investing $222 million in a multi-metal recycling facility at the Tsumeb smelter in Namibia. The facility will have an annual processing capacity of 200,000 tons and will produce 33 tons per year of zone-melting grade germanium, 11 tons per year of 99.9% industrial-grade gallium, and 10,900 tons per year of zinc. This ambitious project will be built in two phases and is expected to operate for 15 years. However, detailed launch dates are still to be disclosed.

The polymetallic slag at the Tsumeb smelter is estimated to contain substantial quantities of germanium, gallium, and other metals, including zinc and copper, making it an attractive site for advanced metal recycling and extraction. Sinomine’s investment reflects the growing global demand for germanium and gallium, both of which have seen price increases following China’s introduction of export licensing schemes in August 2023. These metals are considered critical for high-tech applications, and their strategic importance has driven companies worldwide to diversify their supply sources.

The Global Significance of Germanium and Gallium

Germanium, used extensively in industries ranging from telecommunications to clean energy, is a strategic resource that is primarily produced in China, which has been reducing its export volume. The global reserves of germanium are estimated at just 8,600 tons, according to the US Geological Survey. Gallium, which is essential for electronics and solar technology, is also in high demand. Sinomine's strategic investments in germanium and gallium facilities will position the company to capitalize on the rising global need for these critical materials, while reducing its reliance on Chinese supply chains.

Conclusion

Sinomine’s investment in copper and multi-metal recycling projects in Zambia and Namibia highlights its forward-thinking approach to securing a diverse range of valuable resources. As global demand for copper, germanium, and gallium grows, Sinomine is positioning itself as a key player in the African mining sector. With an expanding footprint across the continent, the company is set to shape the future of metal production and recycling, supporting industries from renewable energy to electronics.

Heungkong Wanji gallium smelter planned in Henan to boost semiconductor supply

Luoyang Heungkong Wanji

Heungkong Wanji gallium smelter will add 60 t per year in Henan. The plant will sit inside a 1.2mn t/yr alumina complex. Local authorities opened an environmental review on 11 June. The company has not announced a commissioning date.

China’s alumina producers are accelerating gallium projects to capture value. Prices jumped in 2022 with EV magnet demand. Export controls since August 2023 also reshaped supply strategies. Therefore, producers see strategic and commercial incentives to scale.

Capacity wave and competitive landscape

A capacity wave is building across Guizhou and beyond. Guizhou Haihao launched 50 t per year in September 2024. Guizhou Huajin added another 50 t per year last November. Guizhou Galuminium started a 40 t per year line in 2022. Guizhou Qiya is adding 20 t per year to reach 60 t. Minor metals producer Vital opened an 80 t per year plant in 2025. Together, these projects signal rising domestic supply.

Market implications and policy context

Rising capacity could pressure prices while improving availability for downstream users. However, export licensing can still influence trade flows. Integrated alumina sites reduce unit costs for gallium recovery. Therefore, the Heungkong Wanji gallium smelter may gain cost advantage. Meanwhile, global buyers seek stable sources for semiconductors and power electronics.

The Metalnomist Commentary

This project adds another pillar to China’s gallium-by-alumina strategy. Execution will hinge on recovery yields, product specs, and permitting pace. Watch how export policy interacts with a fast-rising domestic capacity base.

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.

Korea Zinc Tennessee Smelter Gains FAST-41 Support for Critical Minerals Refining

Korea Zinc

Korea Zinc Tennessee smelter plans have gained federal permitting support after the US Permitting Council added Project Crucible to FAST-41 coverage. The designation is intended to speed permitting for the proposed smelting and refining facility in Clarksville, Tennessee.

The Korea Zinc Tennessee smelter would produce 12 non-ferrous metals, including zinc, copper, lead, antimony, gallium and germanium. It would also produce semiconductor-grade sulfuric acid, making the project strategically relevant to metals, chemicals and semiconductor supply chains.

The Korea Zinc Tennessee smelter is significant because it would be the first large-scale domestic zinc refinery built in the US since the 1970s. It also reflects Washington’s effort to rebuild domestic refining capacity for critical minerals and reduce dependence on overseas processing.

Project Crucible is planned as a $7.4bn investment. Korea Zinc announced the project in December in a joint venture with the US commerce and defense departments after acquiring the adjacent East Tennessee and Mid Tennessee mining complexes and the Clarksville smelter from Trafigura-owned Nyrstar.

Project Crucible Targets a Multi-Metal Refining Gap

Project Crucible is designed to process 1.1mn t/yr of raw materials and produce 540,000 t/yr of finished products. Korea Zinc expects to source feedstock mainly from the US and other North American sources.

This feedstock strategy matters because the US has mine supply and scrap flows, but lacks enough large-scale refining and separation capacity for several strategic materials. Project Crucible could help close that midstream gap.

The product mix is especially important. Zinc, copper and lead provide scale, while antimony, gallium and germanium add critical minerals value.

Gallium and germanium are strategically sensitive because they are used in semiconductors, fibre optics, infrared systems, defence electronics and advanced manufacturing. Antimony is also important for flame retardants, ammunition, lead alloys and military applications.

The facility’s semiconductor-grade sulfuric acid output adds another layer of industrial importance. High-purity sulfuric acid is a key chemical input for semiconductor manufacturing and advanced electronics.

Korea Zinc plans to base the facility on its Onsan smelter in South Korea. That gives the project an established technical reference point and strengthens its credibility as a complex multi-metal refining platform.

FAST-41 Status Supports US Industrial Supply Security

FAST-41 coverage gives Project Crucible a more coordinated federal permitting path. The Permitting Council also signed a memorandum of understanding with Tennessee to align federal and state permitting efforts.

The US Department of Defense will primarily oversee permitting for the project. That role underlines the national security importance of domestic critical minerals refining.

Korea Zinc expects construction to begin in 2027. Phased operations are scheduled to start in 2029 with zinc, lead and copper production.

Finished products are expected to move to US customers by rail. This gives the project a domestic logistics route and supports the broader goal of building mine-to-market North American supply chains.

The project fits a wider US strategy. Washington is trying to accelerate permitting, use defence-linked financing and support domestic refining capacity for materials used in semiconductors, defence, energy infrastructure and manufacturing.

For Korea Zinc, the project offers a major entry into US critical minerals processing. For the US, it provides a rare chance to add large-scale refining capacity across both base metals and strategic minor metals.

The Metalnomist Commentary

Project Crucible shows that the US critical minerals challenge is increasingly about refining, not only mining. If Korea Zinc can execute the Tennessee smelter on schedule, it could become one of the most important non-Chinese multi-metal refining assets in North America.

Sinomine Acquires Tsumeb Smelter to Boost Germanium Production

Sinomine Resource

Chinese mining giant aims to enhance its portfolio with germanium from Namibian facility

Sinomine Resource, a major Chinese mining company, has finalized the acquisition of the Tsumeb smelter in Namibia from Dundee Precious Metals. This move is part of Sinomine's strategy to expand its germanium production capabilities. The Tsumeb smelter, with an initial capacity of 260,000 tons per year for blister copper, is set to be upgraded to handle 370,000 tons per year. It is one of the few smelters equipped to process complex concentrates like high arsenic-copper concentrate.

Resource Potential and Strategic Focus

The smelter's polymetallic slags contain an estimated 2.94 million tons of ore, which includes 746 tons of germanium, 410 tons of gallium, and other significant metals. Germanium is crucial for various industries, including information and communication technology, biological science, aviation, and new energy sectors. With global germanium reserves at 8,600 tons, China has prioritized this resource as strategic.

Sinomine will conduct a feasibility study to upgrade the smelter and integrate germanium and zinc production, aiming for commercial output in the near future. The company has not provided additional details on the project's timeline.

Copper Supply Chain Fragility Is Underpriced Despite Price Rally

Ivanhoe

Copper supply chain risk is still being underpriced even after London Metal Exchange prices rallied above $13,000/t, according to Ivanhoe Mines chairman Robert Friedland. He warned that higher prices alone will not quickly unlock new mine investment or solve the operational bottlenecks now shaping copper supply.

The copper supply chain is facing a more complex problem than headline market balances suggest. Friedland pointed to sulphur, sulphuric acid, diesel and other critical inputs as increasingly important constraints for mining operations, especially in Africa.

The copper supply chain is particularly exposed in the Democratic Republic of Congo, where a large share of production depends on acid leaching. If sulphuric acid availability tightens further, Friedland said about half of the DRC’s low-grade leached copper could be at risk unless higher copper prices offset sharply higher acid costs.

This warning comes as the Middle East conflict affects copper markets indirectly. The immediate threat is not concentrate supply, but sulphur-linked cost inflation that can raise operating costs for solvent extraction and leaching operations.

Sulphuric Acid and Diesel Risks Expose Mining Cost Vulnerability

Sulphuric acid has become a central issue for copper supply because much of the DRC’s production relies on acid leaching. A prolonged disruption in sulphur flows could affect roughly 3mn t/yr of DRC copper output, making the country one of the most exposed parts of the global copper market.

The DRC’s vulnerability is different from that of traditional concentrate producers. Concentrate supply depends on mining, milling, logistics and smelter demand. Leached copper also depends on steady sulphur or sulphuric acid access, which creates another layer of supply-chain risk.

Ivanhoe’s Kamoa-Kakula complex is unusually positioned because it produces sulphuric acid as a by-product rather than relying only on external supply. The operation produced more than 100,000t of sulphuric acid in the first quarter of 2026, with annual output expected to reach 600,000-700,000 t/yr once the new smelter is fully ramped up.

That acid production gives Ivanhoe a strategic advantage. It can reduce exposure to imported acid costs while supporting copper output in a market where other DRC producers may face tighter reagent availability.

Diesel is another operational risk. Remote mines depend on diesel for haulage, power generation and logistics, especially where grid access is weak or transport routes are long.

Friedland said highly exposed mining firms should consider securing up to a year of diesel supply. He also argued that the DRC may be less vulnerable than some expect because refined products can arrive through India, Nigeria and southern Africa.

Still, the full operational impact may not yet be visible. Supply-chain shocks often appear first through higher costs, longer lead times and working-capital pressure before they become production losses.

This is why the copper market may be misreading risk. Visible inventories and annual balances can suggest moderate surplus, while the physical supply chain becomes more fragile beneath the surface.

A copper price above $13,000/t helps margins, but it does not immediately create acid, diesel, spare parts, qualified labour or new mine capacity. Mine investment still depends on permitting, capital cost, political risk and long development timelines.

AI, Data Centres and Critical Metals Raise Copper’s Strategic Value

Friedland linked copper’s long-term importance directly to electrification, cooling systems, data centres and artificial intelligence. These sectors are turning copper from a conventional industrial metal into a strategic infrastructure material.

AI data centres need large amounts of power infrastructure. That means more copper for grids, substations, transformers, cooling systems, cabling, backup power and electrical distribution.

The growth of AI also reinforces demand for metals beyond copper. Friedland highlighted gallium, scandium, dysprosium, rhenium and tantalum as thinly traded materials with low liquidity but high industrial dependence.

This is an important market signal. The next phase of industrial competition will not depend only on bulk metals. It will also depend on access to small-volume strategic materials that support semiconductors, aerospace, defence, magnets and high-performance alloys.

Copper remains the anchor metal because it connects electrification, grid expansion, industrial automation and data infrastructure. Friedland described copper as the “king of metals” because no large-scale energy transition can move without it.

However, copper’s strategic value also exposes the market to policy pressure. The US is beginning to understand mining’s national security role more clearly, especially as domestic supply concentration and import dependence become more visible.

Market participants expect moderate global copper surpluses this year, helped by last year’s supply windfall. But US physical balances are expected to remain tight, with the CME-LME arbitrage reopening to encourage flows into the country.

That regional tightness matters. Copper may look balanced globally, while specific markets face procurement pressure because of tariffs, logistics, exchange spreads, domestic manufacturing needs or strategic stockpiling.

The broader lesson is that copper pricing must account for supply-chain resilience, not only mine output. A mine that lacks acid, fuel or logistics capacity cannot deliver metal reliably, even if ore is available.

For investors, this strengthens the value of hard assets with low obsolescence. Mines, smelters, acid plants, power infrastructure and logistics corridors are becoming more valuable as supply chains become less predictable.

For manufacturers, copper procurement is becoming a strategic function. Buyers linked to grids, data centres, defence, cooling systems and energy infrastructure will need more secure supply agreements, not only exposure to exchange prices.

The Metalnomist Commentary

Friedland’s warning cuts through the headline copper rally: the market is pricing metal, but not enough supply-chain fragility. Copper’s next constraint may come less from ore availability and more from acid, diesel, logistics and the minor metals needed to build the electrified economy.
