Aclara REE Separation Pilot Plant Advances US Heavy Rare Earth Supply Chain

Aclara REE

Aclara REE separation pilot plant commissioning in Virginia marks an important step toward building a non-China rare earth processing route for heavy and light rare earth oxides. Chilean rare earths producer Aclara Resources has opened the pilot facility in Blacksburg as part of its strategy to create a vertically integrated rare earth supply chain.

The plant will process mixed rare earth carbonates sourced from Aclara’s ionic clay deposits in Brazil and Chile. This gives the company a route to connect South American rare earth resources with US-based separation technology and future downstream supply.

The Aclara REE separation pilot plant is designed to produce separated dysprosium, terbium, and neodymium-praseodymium. First light rare earth oxide output is scheduled for May 2026, while heavy rare earth oxide output is expected in August 2026.

Virginia Pilot Plant Targets Critical Magnet Materials

The Virginia facility matters because rare earth separation remains one of the most difficult and strategically sensitive parts of the supply chain. Mining or producing mixed carbonate is only the first step; the real value is created when individual rare earth oxides are separated to commercial specification.

Dysprosium and terbium are especially important because they are used to improve high-performance permanent magnets. These magnets support electric vehicles, wind turbines, robotics, defense systems, and advanced industrial equipment.

Neodymium-praseodymium is also central to magnet production. By targeting both light and heavy rare earth oxides, Aclara is positioning the pilot plant as a technical bridge between upstream ionic clay resources and downstream magnet material demand.

Louisiana Facility Could Scale Aclara’s US Processing Strategy

The Aclara REE separation pilot plant will support engineering, ramp-up, and process optimization for the company’s planned commercial separation facility in Louisiana. That project requires capital investment of $277 million and is scheduled to begin operations by mid-2028.

The collaboration with Virginia Tech and Argonne National Laboratory strengthens the technical base behind the project. It also aligns Aclara with US efforts to build domestic rare earth processing capacity for materials that remain heavily exposed to China-controlled supply chains.

For the market, the key question is whether Aclara can move from pilot output to reliable commercial-scale separation. If successful, the Louisiana facility could become a meaningful new processing node for dysprosium, terbium, and neodymium-praseodymium outside Asia.

The Metalnomist Commentary

Aclara’s Virginia pilot plant shows that rare earth supply security depends on separation technology, not only resource ownership. The company’s model also highlights a practical route for linking Latin American deposits with US processing capacity and strategic magnet demand.

Aclara HREE separation plant anchors US heavy rare earth strategy

Aclara

Aclara HREE separation plant plans to reshape the US heavy rare earths supply chain by targeting dysprosium and terbium for EVs. The Aclara HREE separation plant in Louisiana will draw feed from ionic clay deposits in Brazil and Chile. As a result, the Aclara HREE separation plant positions the US to cut reliance on Chinese-controlled heavy rare earths.

Louisiana HREE hub to cover most US dysprosium and terbium demand

Aclara will invest $277mn in a Louisiana heavy rare earths separation facility focused on dysprosium, terbium and NdPr oxides. The company targets completion in 2027 and aims to supply more than 75pc of US dysprosium and terbium demand for EVs by 2028. This volume would materially shift US sourcing patterns for critical magnet materials.

The project benefits from approximately $46.4mn in state tax incentives and grants, underlining Louisiana’s push to attract strategic materials investments. Meanwhile, Aclara plans to integrate the separation plant with a future metals and alloys facility on the same site. This integrated footprint could support a mine-to-magnet pathway once downstream alloying and magnet projects materialise.

Ionic clay deposits in Brazil and Chile underpin feedstock security

Aclara will supply the Louisiana plant with feed from two ionic clay deposits located in Brazil and Chile. These deposits are expected to be operational in 2028, slightly lagging the HREE plant start-up. The company targets annual production of about 200t of dysprosium, 30t of terbium and 1,400t of separated neodymium-praseodymium oxide.

In Brazil, Aclara has already started de-risking its flowsheet through pilot operations. The Carina Project pilot plant in Goiania began running in April and produced its first rare earths concentrate in June. The firm also expects up to $5mn in support from the US International Development Finance Corporation, signalling strong strategic interest from Washington. Together, the Louisiana plant and South American deposits outline a multi-node HREE supply chain geared to long-term EV and magnet demand.

US HREE separation plant sits at the heart of magnet supply realignment

Aclara’s US HREE separation plant joins a growing list of projects aimed at diversifying global heavy rare earths supply. However, few projects are configured to supply such a large share of the domestic dysprosium and terbium market. If timelines hold, Louisiana could become a cornerstone hub feeding US and allied magnet manufacturers before the end of the decade.

At the same time, building metals and alloys capacity on-site raises the prospect of deeper value capture within US borders. Therefore, the project’s success will be judged not only on tonnage but also on how effectively it links to magnet makers and OEMs. For automakers and defense contractors, locking in offtake from a US-based HREE separation plant may become a strategic priority.

The Metalnomist Commentary

Aclara’s HREE separation investment in Louisiana illustrates how quickly the heavy rare earth landscape is evolving under geopolitical pressure. The combination of ionic clay feed from Brazil and Chile with US separation capacity provides a diversified platform that investors and OEMs will watch closely. If execution matches ambition, this project could become a reference model for trans-regional critical mineral partnerships anchored in US downstream processing.

Aclara Rare Earth Oxides Plan Links Brazil Mining to US Separation

aclara

Aclara rare earth oxides production plans have been reaffirmed for the Carina project in Brazil, strengthening the company’s role in the emerging Americas rare earth supply chain. The Brazilian rare earth producer expects to produce more than 4,300 t/yr of rare earth oxides from 2028.

Aclara rare earth oxides output is expected to average 4,378 t/yr contained in mixed rare earth concentrate. The planned product mix includes 1,191 t/yr of neodymium-praseodymium, 156 t/yr of dysprosium and 27 t/yr of terbium.

Aclara rare earth oxides are strategically important because NdPr, dysprosium and terbium are key inputs for high-performance permanent magnets. These magnets are used in electric vehicles, wind turbines, robotics, defence systems and advanced industrial motors.

The Carina project is expected to have an 18-year mine life. Production costs are estimated at $29.20/kg of rare earth oxide produced, giving investors and customers a clearer basis for assessing the project’s long-term competitiveness.

Carina Project Adds Heavy Rare Earths to the Americas Supply Base

The Carina project’s value is not limited to light rare earths. Its mixed rare earth concentrate also contains several heavy rare earth elements that are difficult to secure outside China-linked supply chains.

Aclara expects annual output to include 173 t of samarium, 176 t of gadolinium, 10 t of lutetium and 1,160 t of yttrium. These materials add strategic depth to the project because heavy rare earth supply remains highly concentrated and increasingly sensitive to export controls.

Dysprosium and terbium are especially important for magnet performance. They improve heat resistance and magnetic stability in demanding applications such as EV traction motors, wind turbine generators and defence electronics.

The project therefore fits a wider western effort to build alternative rare earth supply chains. Brazil offers mineral potential, while the US provides downstream policy support and processing infrastructure incentives.

Construction at Carina is scheduled to begin in the third quarter of 2026. Initial output is expected in the second half of 2028, followed by ramp-up in 2029.

Louisiana Separation Plan Builds Downstream Magnet Chain

Aclara plans to send material from Carina to Louisiana for separation and processing. The US site will produce rare earth metals and alloys, moving the project beyond mine supply into downstream magnet material preparation.

This structure matters because rare earth security depends on more than mining. Mixed rare earth concentrate must be separated, refined, converted into metals and alloyed before it can support permanent magnet production.

The Louisiana processing route could therefore create a more integrated Brazil-US rare earth chain. It links Brazilian ionic clay-style rare earth resources with US separation, metal and alloy capacity.

Public-sector support strengthens the project’s strategic profile. The US International Development Finance Corporation provided $5mn for Carina’s development, while Louisiana granted $46mn in tax incentives to accelerate the separation project.

For western magnet manufacturers, Aclara’s model offers potential supply diversification. The company could provide NdPr, dysprosium and terbium units into a market where downstream users are actively seeking non-China material.

However, execution remains critical. The project must move through construction, commissioning, ramp-up and qualification before it can become a reliable supply source for magnet makers and strategic customers.

The Metalnomist Commentary

Aclara’s plan shows that rare earth competitiveness now depends on linking mine output with separation and metal conversion. The Brazil-Louisiana route could become strategically important if it delivers heavy rare earth volumes into the Americas magnet supply chain.

Aclara Brazil Rare Earths Pilot Plant Launches to Bolster Global Supply Chain

Aclara Resources

The Aclara Brazil rare earths pilot plant has officially started operations, marking a strategic milestone for critical mineral development in South America. Aclara Resources, a Canadian-based mining firm, invested R30mn ($5.3mn) to develop the pilot facility in Nova Roma, located in Brazil’s Goias state. The semi-industrial scale plant will process 250 metric tonnes per year of ionic clays, producing concentrate with over 95% purity.

Supplying Rare Earths for the EV Revolution

Aclara’s plant will extract both heavy and light rare earth elements, including dysprosium, terbium, neodymium, and praseodymium. These metals are essential to electric vehicle (EV) production, wind turbines, and high-performance magnets. Aclara stated the plant could support the manufacturing of up to 5 million EVs annually. The company emphasized its environmentally responsible extraction process as part of its commitment to sustainable mining.

Brazil Emerges as a Rare Earths Powerhouse

Brazil continues to attract investment in rare earth and critical mineral projects. Production at Mineracao Serra Verde’s Goias facility, with a 5,000t/year rare earth oxide capacity, began in late 2023. With the Aclara Brazil rare earths pilot plant now operational, Brazil strengthens its position as an emerging alternative to China in the global rare earth supply chain.

The Metalnomist Commentary

The launch of the Aclara Brazil rare earths pilot plant highlights Brazil’s increasing relevance in the global critical mineral landscape. As countries seek diversified rare earth sources, Brazil’s sustainable projects will play a key strategic role in decarbonization and supply security.

Aclara heavy rare earths funding advances Carina project in Brazil

Aclara Resources

Aclara heavy rare earths funding will accelerate the Carina project in Brazil. Aclara heavy rare earths funding comes from the US DFC, totaling up to $5mn. Aclara heavy rare earths funding targets the feasibility study now underway.

What the DFC funding enables

The new capital supports a feasibility study launched in July 2025. The study is due by the end of the first quarter of 2026. The DFC is a US government development finance agency. The instrument can convert into equity under set conditions. Conversion triggers include a single $50mn+ round or $75mn across rounds within 12 months. The path anticipates construction finance for Carina.

Why this matters for US-aligned supply chains

Aclara runs a vertically integrated rare earth model across Brazil and Chile. The company plans a US separation facility for mixed carbonates into oxides. It also partners with Chile’s CAP to produce rare earth metals and alloys. The package supports heavy rare earths outside China and diversifies supply. The study will define scale, flowsheet, costs, and ESG performance.

The initiative strengthens strategic cooperation between North and South America. It aligns with efforts to localize midstream and metal production. It also positions Aclara to pursue offtakes with magnet supply chains.

The Metalnomist Commentary

DFC participation de-risks early studies and signals policy support for heavy rare earths. Watch the equity conversion triggers and downstream US separation timing. Execution will hinge on permitting, capex discipline, and securing long-lead equipment.

Aclara-Stanford rare earth partnership to accelerate HREE supply

Aclara

Aclara-Stanford rare earth partnership targets AI-driven discovery of heavy rare earths. The Aclara-Stanford rare earth partnership will deploy predictive models to map ionic clays. As a result, the effort aims to build a reliable HREE supply chain for magnets.

AI-driven exploration and Mineral-X roadmap

The partners will collaborate through Stanford’s Mineral-X, focusing on regolith and ionic-clay mineralization. They will exchange technical data, co-author papers, and run pilot projects. Meanwhile, predictive modeling should sharpen drill targets and cut discovery risk. Therefore, the Aclara-Stanford rare earth partnership links research to commercialization faster.

Integrated mining-to-magnets plan and Brazil timeline

Aclara pursues an integrated strategy from mining to magnet production. Its Carina Project in Goiás targets 191 t/yr of DyTb and 4,736 t/yr of total rare earth oxides. Operations are expected to start in 2028, supporting EV motor and wind magnet demand. Consequently, Carina could diversify non-Chinese heavy rare earth supply for OEMs.

Global OEMs want localized, resilient magnet materials. However, heavy rare earth elements remain constrained and price sensitive. By combining AI targeting and staged pilots, the partners can lower exploration costs. As a result, bankability may improve for HREE projects aligned with clean-energy supply chains.

The Metalnomist Commentary

AI-guided geology is moving from concept to competitive advantage in rare earths. If Carina delivers Dy/Tb as planned, this tie-up could reset HREE sourcing dynamics for Western magnet makers.

Aclara Produces First REE Concentrate in Brazil with Circular Mining Technology

Aclara Resources

Pilot Plant Targets Heavy Rare Earth Output Through August

Aclara Resources has produced its first rare earth elements (REE) concentrate at a pilot plant in Brazil, marking a key milestone in its integrated mining-to-magnet strategy. In May, the facility processed 14 metric tonnes (t) of ionic clay, yielding concentrates containing dysprosium (Dy) and terbium (Tb). Operations will continue through August, with up to 200t of clays expected to generate approximately 150kg of heavy REE concentrates.

Sustainable Mining and Global Expansion Plans

The Brazilian pilot plant uses Aclara’s proprietary Circular Mineral Harvesting technology, which removes the need for tailings dams and reduces environmental impact. This facility is part of a broader strategy encompassing the Carina Project in Goias, Brazil, and the Penco Module in Chile’s Biobio Region. Aclara also plans to establish a rare earth separation facility in the US. The Carina Project aims to produce 4,736t/yr of total rare earth oxides, including 191t of DyTb, with commercial operations targeted for 2028.

The Metalnomist Commentary

Aclara’s move to pilot REE production in Brazil positions it as a competitive player in the heavy rare earth market. Its low-impact extraction method addresses growing environmental concerns, while its integrated supply chain strategy could help secure critical minerals for the global magnet industry. The success of the Carina Project will be pivotal in determining its long-term market influence.

Aclara Expands Rare Earth Resources in Brazil

Chile-based rare earth explorer Aclara Resources has significantly bolstered its mineral resources at its Carina project in Brazil, reporting a 77% increase. The updated inferred mineral resource now stands at 298 million metric tonnes, a substantial rise from the 168 million tonnes estimated in December, the company announced today.

Aclara also reported a notable 69% increase in the contained amounts of magnetic elements, with significant growth in heavy rare earths such as dysprosium and terbium (DyTb), as well as light rare earths neodymium and praseodymium (NdPr).

Located in Brazil’s central Goias state, the Carina module is poised for further development, with plans to establish a semi-industrial pilot plant by the second quarter of next year. According to the US Geological Survey (USGS), Brazil is home to some of the world’s largest rare earth reserves.

Aclara Resources specializes in heavy rare earth mineral resources found in Ion-Adsorption clay deposits. The company’s development projects include the Penco module in Chile’s Bio-Bio region and the Carina module in Brazil.

US-made rare earth magnets shipped as eVAC reshoring milestone

eVAC

US-made rare earth magnets reached the commercial market as eVAC shipped its first batch from Sumter, South Carolina. The shipment marks a visible step in US efforts to reshore permanent magnet production. Therefore, US-made rare earth magnets now move from policy ambition to delivered product.

eVAC said the delivery represents the first commercial rare earth magnet production in the US. However, the company did not disclose shipment volumes. Meanwhile, customers in EVs, wind, and industrial motors keep pushing demand for stable neodymium supply.

Sumter South Carolina magnet plant scales fast toward 2026 output

The Sumter South Carolina magnet plant is ramping toward 2,000 metric tonnes per year by the first quarter of 2026. eVAC also plans to expand to six times that level in later phases. As a result, the Sumter South Carolina magnet plant could become a cornerstone supplier for North American manufacturing.

eVAC operates as a subsidiary of Germany’s Vacuumschmelze. That ownership adds technical depth and process know-how for high-performance magnet production. Meanwhile, US buyers value local manufacturing for lead-time and security benefits.

eVAC neodymium iron boron magnets link upstream feedstock to US demand

eVAC neodymium iron boron magnets rely on rare earth feedstock from MP Materials. MP supplies neodymium-praseodymium materials sourced from the Mountain Pass mine in California. Therefore, eVAC neodymium iron boron magnets connect US mining and processing to downstream magnet assembly.

eVAC also points to additional supplier partnerships, including Ucore and Aclara, to support expansion. However, qualification cycles and consistent feedstock specifications will still shape ramp speed. As a result, the reshoring narrative will depend on repeatable volumes and customer approvals.

The Metalnomist Commentary

This shipment matters because magnets sit at the chokepoint of electrification supply chains. However, real resilience requires scale, multiple qualified feed sources, and stable pricing. Therefore, eVAC’s 2026 ramp will become the true stress test for US-made rare earth magnets.

China to Overpower Brazil in Rare Earths Through 2050

Brazil in Rare Earths

China to overpower Brazil in rare earths as processing capacity stays highly concentrated in China. Brazil holds vast reserves, but processing lags. Therefore, China to overpower Brazil in rare earths remains the base case through 2050. Brazil eyes offshore and onshore reserves to raise output. However, processing bottlenecks still define market power.

Processing Dominance Shapes Market Power

China to overpower Brazil in rare earths reflects processing, not geology. China handled 90% of rare earth processing in 2022. Malaysia held 9% and Estonia 1%. Meanwhile, China produced 68% of rare earths in 2022. The US and Australia followed at 11% and 9%. IEA sees China’s magnet REE mine supply up 24% by 2035. Australia may quadruple output to 14,570t by 2035. Yet processing concentration keeps China’s strategic lead intact.

Brazil’s Resource Scale Meets Early-Stage Industry

Brazil holds 23% of global rare earth reserves. It also holds 26% of graphite and 94% of niobium. Even so, commercial production is nascent. Serra Verde is Brazil’s only REE producer today. New entrants target Brazil’s clays and carbonatites. REA and Aclara plan Dy, Tb, and NdPr projects. Government ambitions include the Rio Grande Rise offshore. Success still requires midstream plants and clean leach circuits.

The Metalnomist Commentary

Processing remains the real chokepoint, not reserves. Brazil’s path runs through solvent extraction investment and ESG-credible reagents. Watch pilot circuits, offtakes, and financing signals that enable non-China midstream scale.

Serra Verde Rare Earth Financing Strengthens Brazil’s Position in Heavy Rare Earth Supply

DFC, Brazil

Serra Verde rare earth financing marks a major strategic step for Brazil’s rare earth industry. The US International Development Finance agency has provided a $565mn package to Serra Verde. The funding includes an option for the US government to take a minority equity stake. As a result, Serra Verde rare earth financing now carries both industrial and geopolitical weight.

This matters because Serra Verde is already producing from its Pela Ema ionic clay deposit in Brazil. The operation entered commercial production in 2024 and currently produces 5,000 t/yr of total rare earth oxides. Its output includes dysprosium, erbium, neodymium, and praseodymium. Therefore, Serra Verde rare earth financing supports an existing project rather than a distant concept.

The funding also arrives at a time when western governments are moving more aggressively into critical minerals. Recent DFC activity has already expanded into copper, tungsten, and other strategic materials. Consequently, Serra Verde rare earth financing fits a much broader push to secure non-Chinese supply routes.

Brazil Rare Earth Project Gains Capital for Expansion and Strategic Relevance

The Brazil rare earth project will use the funding to refinance existing loans and expand capacity. Serra Verde aims to raise output to 6,500 t/yr of total rare earth oxides by 2027. That increase may look modest in absolute terms, but it matters in a market where diversified rare earth supply remains scarce. As a result, the Brazil rare earth project gains both financial flexibility and a clearer growth path.

The ionic clay nature of the deposit adds further importance. Ionic clay rare earths are especially relevant because they can contain valuable magnet and heavy rare earth elements. That makes Serra Verde more strategically attractive than a simple bulk rare earth project. Therefore, Serra Verde rare earth financing strengthens a part of the supply chain that many western buyers want to expand.

The equity option also deserves attention. A financing structure that includes a possible government minority stake suggests unusually strong strategic interest. This is not only about debt support or project refinancing. Meanwhile, it signals that Brazil’s rare earth sector is moving closer to formal alignment with western supply chain security goals.

Heavy Rare Earth Supply Diversification Gives Brazil More Strategic Value

Heavy rare earth supply remains one of the most sensitive areas in the critical minerals market. Dysprosium and similar elements are essential for advanced magnets and high-performance industrial uses. Projects that can produce these materials outside concentrated supply chains attract far more attention than simple reserve size alone. Consequently, Serra Verde rare earth financing helps position Brazil more clearly in the strategic supply map.

Brazil’s wider resource base reinforces that story. The country holds one of the world’s largest rare earth reserve positions and is already drawing more developer attention. Companies such as Aclara, Brazilian Rare Earths, and Meteoric are also advancing projects there. Therefore, Serra Verde rare earth financing may become a signal for broader investment momentum across Brazil.

The broader implication is clear. Supply chain diversification is no longer only about finding resources. It is about financing operating projects, expanding production, and tying new supply into aligned trade relationships. As a result, Brazil is becoming more important not just as a resource holder, but as a future processing and supply partner.

The Metalnomist Commentary

This deal matters because it supports a producing rare earth asset with real expansion potential. Serra Verde is now moving beyond startup status and into strategic scale-up territory. If output rises as planned, Brazil could gain a much stronger role in non-Chinese rare earth supply over the next few years.

Brazil Critical Minerals Processing Moves Closer to a US-Backed Expansion

US, critical minerals in Brazil

Brazil critical minerals processing is moving closer to a new strategic phase. The United States is now openly discussing financing and technical support for Brazil critical minerals processing. Washington sees Brazil as an essential partner in a more resilient Western supply chain. As a result, Brazil critical minerals processing is becoming a serious geopolitical and industrial priority.

This shift matters because Brazil has large reserves but limited downstream scale. The country holds major positions in niobium, rare earths, graphite, nickel, and lithium. Yet Brazil still contributes only a small share of global rare earth production. Therefore, the next stage of the market will depend less on geology and more on industrial buildout.

The US focus appears especially clear in heavy rare earths. Projects such as Serra Verde and Aclara already show where this strategy may go. Both are tied to mixed rare earth products with higher dysprosium and terbium content. Consequently, heavy rare earth processing in Brazil is becoming more central to future magnet supply chains.

US-Brazil Critical Minerals Partnership Is Moving Beyond Mining

US-Brazil critical minerals partnership is now shifting from resource interest toward processing ambition. US officials said financing from the Development Finance Corporation and technical cooperation could support that next step. That matters because processing is where more value stays inside the supply chain. As a result, Brazil is being positioned as more than a raw materials source.

This approach also fits wider US strategy in Latin America. Washington has already signed critical minerals agreements with several regional partners. Brazil stands out because of its resource scale and industrial sophistication. Therefore, it offers stronger conditions for building midstream capacity than many other jurisdictions.

However, the political structure will matter. Brazil would still need to allow foreign-backed processing development on its territory. That means any real progress will require policy alignment as well as financing. Meanwhile, both governments appear to understand that strong partnerships will decide whether this vision becomes real.

Brazil Rare Earth Value Chain Depends on Industrialization, Not Exports Alone

Brazil rare earth value chain expansion is also a domestic political priority. President Lula has made it clear that Brazil does not want to remain a simple exporter of critical minerals. He wants foreign companies to build downstream industry inside the country. That message aligns closely with demands from Brazilian market participants.

The same logic applies beyond rare earths. Lithium producers and industry groups also want policies that support a full end-to-end value chain. They argue Brazil has the resource base to become a global critical minerals leader. However, the country still lacks stronger fiscal incentives for midstream and downstream investment. Therefore, Brazil critical minerals processing may advance only if industrial policy becomes more competitive.

That is why current US interest matters so much. External financing can help, but it cannot replace local policy support. If Brazil combines foreign capital with domestic industrial incentives, it could move far higher in the global value chain. As a result, Brazil rare earth value chain development may become one of the most important critical minerals stories in the Americas.

The Metalnomist Commentary

Brazil now faces a clear strategic choice. It can stay rich in reserves but light in processing, or it can push deeper into value-added industry. If US backing and Brazilian industrial policy move together, Brazil could become one of the West’s most important critical minerals processing hubs.
