DOE Deploys $10 Million Across Seven CMI Hub Projects Targeting Gallium, Heavy Rare Earths, and Copper Recovery

Introduction

The U.S. Department of Energy's Office of Critical Minerals and Energy Innovation announced on August 26, 2026, that it had selected seven projects for up to $10 million in combined funding, administered through the Critical Materials Innovation Hub (CMI Hub) at Ames National Laboratory. The projects span gallium extraction from industrial waste streams, advanced copper sulfide leaching chemistry, and a molten salt electrochemical process aimed at producing heavy rare earth metals domestically. All seven are classified as early-stage research and development, meaning the work is intended to generate the scientific and engineering foundation needed before pilot or commercial-scale investment becomes viable.

The announcement lands at an unusually charged moment for U.S. critical mineral policy. The temporary suspension of China's full export ban on gallium, germanium, and antimony runs only through November 27, 2026, after which the licensing regime tightens again. A Pentagon procurement deadline on January 1, 2027 bars defense contractors from using rare earth magnets containing any Chinese-origin material. And as I covered in my August analysis of the DOE's $162 million secondary-source recovery awards, federal agencies are now deploying funding in rapid successive tranches rather than waiting for a single omnibus program, reflecting genuine urgency rather than routine grant administration.

Assistant Secretary of Energy Audrey Robertson framed the strategic purpose plainly: 'These seven projects will leverage the Critical Materials Innovation Hub's strong foundation of expertise to address key technical challenges involving heavy rare earth elements, gallium, copper, and other critical materials. This work will unlock new production methods that strengthen domestic supply chains and ensure American manufacturers have access to the materials they need to compete and lead.' DOE spokesperson Maria Payan added application context, noting that gallium is found in high-voltage semiconductors, LEDs, high-strength magnets, space solar photovoltaics, integrated circuits, and optoelectronics, while heavy rare earth elements such as dysprosium and terbium are used to improve the performance of high-strength magnets for wind turbines and electric vehicles.

One important qualification applies to all seven selections: selection for award negotiations is not a commitment by DOE or the CMI Hub to issue funding. Before money flows, DOE and each applicant must complete a negotiation process that the agency may cancel for any reason. That caveat is standard language for competitive federal research programs, but it is worth retaining in any assessment of the initiative's near-term impact.

Four Gallium Projects Pursue a No-New-Mines Strategy

The most structurally significant feature of the August 26 award is that four of its seven projects target gallium recovery from existing industrial streams rather than from new mineral extraction. The logic is straightforward: gallium does not occur in economic primary ores of its own. It is almost exclusively recovered as a byproduct of processing bauxite ore for aluminum, or as a trace constituent of zinc concentrates. The real upstream source of gallium is an alumina refinery or a zinc smelter, not a dedicated mining operation. China has exploited this byproduct architecture for decades, building capture, separation, purification, and quality-control infrastructure alongside its dominant aluminum and zinc industries.

The United States stopped recovering domestic primary gallium in 1987. According to USGS Mineral Commodity Summaries 2026, the country was 100 percent net import-reliant for gallium in 2025. China produced an estimated 900,000 kilograms of primary low-purity gallium in 2025, against world production of roughly the same figure; Japan contributed approximately 3,000 kilograms and Russia roughly 6,000 kilograms. The price divergence created by China's export controls illustrates the leverage this concentration creates: Chinese primary material has stayed near $250 per kilogram, while Rotterdam spot prices for non-Chinese supply had risen to roughly $2,100 per kilogram by early 2026, a ratio of more than eight to one.

The four DOE-selected gallium projects attack this problem from different points in the industrial waste stream. Oak Ridge National Laboratory is developing a solid-phase extraction method to selectively separate and recover gallium from zinc refinery residues, targeting a domestic resource that USGS estimates contains up to 50 parts per million gallium in some ores yet from which no gallium is currently recovered. The University of Illinois Urbana-Champaign is developing redox-adsorbents for the selective electrochemical recovery of gallium from mining byproducts and end-of-life waste, extending the recovery target beyond primary processing to recycled material streams. Indium Corporation is working on an improved ion-exchange resin specifically for gallium extraction from bauxite-alumina processing streams, which are the highest-volume industrial source of gallium globally. FAST Metals is pursuing gallium and rare earth mixed oxides from industrial byproduct residue streams including red mud, the large-volume waste material generated during bauxite-alumina processing.

The red mud angle is particularly notable. Each tonne of alumina produced generates approximately one to two tonnes of red mud, and the United States has accumulated substantial stockpiles from its existing alumina refining operations. Separately, Alcoa has been working to recover gallium and other critical minerals from its own bauxite residue streams, suggesting that the industrial appetite for this approach exists independently of federal funding. The FAST Metals project would add another research vector to that commercial interest. The GaN semiconductor device market alone is projected to expand from $3.06 billion in 2024 to $12.47 billion by 2030, a compound annual growth rate of roughly 27 percent, giving commercial urgency to the supply question these projects are designed to address.

The trade policy backdrop reinforces that urgency. China imposed initial export controls on gallium in 2023, escalated to a full ban on U.S. shipments in late 2024, and then suspended that ban through November 27, 2026, under the terms of the November 2025 U.S.-China trade truce. Exports during the suspension period still require Chinese government licenses, and the clause barring exports to military end-users remains in effect. On January 2, 2025, China's Ministry of Commerce also added key extraction technologies for gallium separation to its export control catalogue, signaling an intent to preserve leverage not just over the metal itself but over the most efficient methods of producing it. That technology control dimension is precisely what the DOE research awards are designed to counteract by developing domestically owned extraction methods.

Case Western's Molten Salt Approach Targets the Hardest Link in the Heavy REE Chain

The single heavy rare earth project in the August 26 package is the most technically ambitious of the seven selections. Case Western Reserve University will develop a process for producing heavy rare earth metals through chloride-based molten salt electrolysis, an electrochemical approach that uses electricity to recover metals from chloride salts rather than relying on the conventional fluoride-based oxide electrolysis or the solvent extraction chemistry that dominates current practice. The project is led by Rohan Akolkar, the Milton and Tamar Maltz Professor of Energy Innovation in the Department of Chemical and Biomolecular Engineering at the Case School of Engineering, and is based on patented molten salt electrolysis technology that Akolkar and his students developed and will now apply to heavy rare earth production at scale.

The specific target metals are dysprosium and terbium, the two heavy rare earths most critical to high-performance sintered NdFeB permanent magnets. Both are used to improve coercivity, the resistance to demagnetization, in magnets operating at elevated temperatures. That property is essential for the traction motors in electric vehicles and the generators in wind turbines. Both elements are also indispensable for defense applications, including the magnets in military drones, missile guidance systems, and naval propulsion. Samarium, lutetium, gadolinium, and yttrium round out the list of heavy rare earths that USGS identifies as among the U.S. mineral supply chains facing the highest disruption risks.

The partner lineup on the CWRU project is unusually strong for an early-stage award. Energy Fuels and MP Materials bring emerging U.S. feedstock and separation capabilities directly into the research team. Energy Fuels has already demonstrated 99.9 percent-pure dysprosium and terbium oxides at its Utah processing facility and is building commercial-scale heavy REE separation capacity there. Ames National Laboratory and Lawrence Livermore National Laboratory contribute national laboratory expertise in rare earth chemistry and materials characterization. That combination of academic invention, national laboratory science, and industry commercialization pathway makes the CWRU project structurally more mature than its early-stage classification might suggest.

The conventional method for separating and reducing rare earth elements relies on solvent extraction processes that use environmentally damaging solvents and can emit potent greenhouse gases. Molten salt electrolysis sidesteps several of those chemistry challenges but introduces its own engineering demands: achieving high purity outputs, competitive energy consumption, acceptable metal yields, and continuous industrial-scale operation. Whether the CWRU approach can meet all four criteria simultaneously is genuinely uncertain at this research stage. But if it does, it would fill what analysts have identified as the hardest remaining chokepoint in America's nascent heavy rare earth supply chain. A country can possess mineral resources, build separation capacity, and even manufacture permanent magnets while still lacking the metallization step that converts separated oxides into the metal alloys that magnet producers actually use. The CWRU project targets exactly that gap.

Two Copper Projects Apply Novel Chemistry to Primary Sulfide Ore Processing

Copper's inclusion in the August 26 awards reflects a significant shift in how the United States categorizes strategic materials. Copper was added to the federal critical minerals list in 2025, one of 10 commodities newly designated in a revised list totaling 60 materials. That designation change matters because it opens the full range of DOE critical minerals funding vehicles to copper research, which had previously been treated as an abundant industrial metal rather than a strategically constrained one. DOE spokesperson Maria Payan summarized the end-use rationale: copper is used in electric grid cables, machines and transformers for power generation and distribution, electronics, and batteries, placing it at the intersection of nearly every major energy transition technology.

Colorado School of Mines is working on improving copper extraction from primary copper sulfides using hydro and bio-hydrometallurgical processes. The target ore type is significant: copper sulfide ores, particularly chalcopyrite, account for the large majority of the world's copper resources but are substantially more difficult to leach using standard acid processes than the oxide ores that have historically supplied heap-leach operations. Developing efficient hydrometallurgical and bio-hydrometallurgical routes to sulfide copper would expand the addressable resource base considerably and reduce reliance on conventional smelting, which carries a heavy energy and emissions footprint.

The University of Arizona is pursuing a different technical path to the same ore type. Its project combines nanobubbles, surfactants, and reactive oxygen species to enhance copper sulfide leaching. The nanobubble approach is designed to increase the surface area contact between leaching agents and ore particles, while reactive oxygen species can accelerate the oxidative dissolution of sulfide minerals. Together with carefully selected surfactants to manage interfacial chemistry, the combination represents a systems-level engineering approach to a problem that individual chemical or physical interventions have not fully solved. Both copper projects remain at the early research stage, but the underlying chemistry questions they address have real commercial stakes given the scale of domestic copper sulfide resources that cannot currently be processed economically through leach-based methods.

CMI Hub in Context: Thirteen Years of Critical Materials Research and a Deepening Federal Commitment

The Critical Materials Innovation Hub, established in 2013 and led by Ames National Laboratory, enters its third multi-year phase with a research infrastructure that few institutions in the world can match for critical materials breadth. The hub integrates expertise from nine national laboratories, more than a dozen universities, and over thirty industry partners. More than 400 students and postdoctoral scholars have participated in its programs, building the workforce pipeline that federal officials routinely identify as a limiting factor in supply chain development. CMI research methods and technologies have won more than a dozen R&D 100 Awards and additional recognition through the Federal Laboratory Consortium and TechConnect.

During its first phase from 2013 to 2018, the CMI focused on critical rare earths including dysprosium, terbium, europium, neodymium, and yttrium, as well as lithium and tellurium. Phase II from 2018 to 2023 expanded the scope to battery materials including lithium, cobalt, manganese, and graphite, and added indium and gallium to the portfolio. Phase III, which began in the last quarter of 2023, reflects the current strategic environment: heavy rare earths, gallium, and copper now occupy the research priority list alongside the battery materials that defined Phase II. That evolution tracks closely with the geopolitical trajectory of the past three years, as China's export controls transformed materials that were once treated as commodity procurement problems into national security concerns.

The August 26 award fits into a dense sequence of 2026 DOE funding actions. In April, the Office of Critical Minerals and Energy Innovation announced a $69 million Critical Minerals and Materials Accelerator focused on industry-led partnerships to prototype and pilot bench-scale processing technologies. In May, a $45.7 million award covered 19 projects addressing domestic supply chain gaps. In July, a $75 million coal-feedstock award targeted secondary-source rare earth extraction. On August 18, the $162 million nine-project announcement covered recovery of scandium, copper, antimony, and rare earth elements from mine tailings and industrial waste. The August 26 CMI Hub award follows just eight days later. Taken together, these tranches represent a federal critical minerals investment pace without precedent in the post-Cold War period. Earlier DOE gallium-specific funding, a separate $6 million initiative aimed at restarting domestic primary gallium recovery for the first time in nearly 40 years, established the research baseline that several of the August 26 projects now build upon.

The Department of Defense has moved in parallel. Multiple conditional loan agreements totaling more than $2 billion through the Office of Strategic Capital have targeted battery cell manufacturing, rare earth magnet makers, and upstream mining companies. The January 14, 2026, White House proclamation on processed critical minerals imports, which cited national security concerns under Section 232 and opened a 180-day trade negotiation window, provided additional policy scaffolding for the accelerated investment pace. The regulatory environment, the trade policy context, and the funding cadence are now moving in the same direction simultaneously, which has not historically been the case for U.S. critical minerals policy.

What the Awards Do and Do Not Accomplish

The $10 million CMI Hub announcement is best understood as a research portfolio investment rather than a supply chain solution. Early-stage R&D funding is the necessary precondition for later pilot and commercial-scale investment, but the distance between a university laboratory demonstration and an operating industrial process is measured in years and hundreds of millions of additional dollars. The USGS has estimated that gallium resources contained in world bauxite deposits exceed one million tons; the constraint is not geologic scarcity but the engineering and economics of extraction from diffuse, low-concentration streams. The CMI Hub projects are designed to generate the technical knowledge that makes those economics more favorable, not to produce gallium or rare earth metals directly.

For gallium specifically, the structural vulnerability is stark enough that even incremental research progress carries meaningful strategic value. China's production capacity of approximately 1.6 million kilograms per year against U.S. primary production of zero creates a dependency that no single funding announcement can resolve. But the combination of new ion-exchange chemistry from Indium Corporation, solid-phase extraction from Oak Ridge, electrochemical redox-adsorbents from the University of Illinois, and industrial byproduct recovery from FAST Metals represents a genuine diversification of the domestic research approach, attacking the problem from four different points in the industrial waste stream simultaneously. If even one or two of those approaches proves commercially scalable, the landscape shifts.

For heavy rare earths, the CWRU molten salt project addresses a chokepoint that has received less attention than upstream mining and separation. Building on my earlier coverage of China Northern Rare Earth's commercial-scale praseodymium sales and the implications for heavy-REE-free magnet technology, the broader lesson is that processing sophistication, not just raw material access, determines supply chain security. The same principle applies to metallization: Energy Fuels can already produce 99.9 percent pure dysprosium and terbium oxides in Utah, but converting those oxides into the metal alloys that magnet manufacturers require remains a capability gap. The CWRU project is explicitly designed to fill that gap through a domestically owned, patented process.

The two copper projects are earlier in their technology maturity arc than either the gallium or heavy REE work, reflecting copper's more recent addition to the critical minerals list. The scientific questions around sulfide leaching are well-defined even if the answers remain elusive, and both Colorado School of Mines and the University of Arizona bring established metallurgical research programs to the work. The commercial stakes are high: unlocking efficient leach-based processing for chalcopyrite and other copper sulfides would reduce the energy intensity and environmental footprint of domestic copper production while expanding the ore types that domestic operations can economically process.

Conclusion: Early-Stage Bets on a Long Game

The DOE's August 26 award of $10 million across seven CMI Hub projects is, in isolation, a modest investment relative to the scale of the supply chain gaps it addresses. Gallium import values were an estimated $15 million in 2025 for the metal itself and $120 million for gallium arsenide wafers; the entire $10 million CMI Hub award is smaller than a single year's wafer import bill. The heavy rare earth supply chain requires capital measured in the hundreds of millions of dollars to reach commercial scale; a university research project, however well-designed, does not directly displace that requirement. Copper demand for energy infrastructure runs into the millions of tonnes annually worldwide.

But the frame of individual award size is the wrong one for evaluating early-stage research investments. The relevant question is whether the portfolio of seven projects is technically well-targeted and organizationally credible. On both counts, the answer is reasonably affirmative. The CMI Hub's thirteen-year track record, its integration of national laboratories with universities and industry partners, and the specific technical approaches selected, all draw on identified gaps in existing domestic capability rather than on speculative science. The partner lineup on the CWRU project in particular, combining Energy Fuels, MP Materials, Ames Laboratory, and Lawrence Livermore with a university team holding patented technology, suggests a project designed with commercialization in mind from the outset.

The larger significance of the August 26 announcement lies in its place within the accelerating 2026 federal funding sequence. The CMI Hub award, the $162 million secondary-source recovery package from August 18, the $75 million coal-feedstock award from July, the $45.7 million May awards, and the $69 million April accelerator together constitute a federal critical minerals research investment program that is substantially larger, faster-moving, and more strategically coherent than anything the United States has deployed in the modern era. Whether that investment pace translates into operational domestic supply before the compliance deadlines of late 2026 and early 2027 arrive is a separate question with a more sobering answer. The research the CMI Hub projects will generate over the next several years is necessary groundwork. It is not, by itself, sufficient to close the gap.
