DOE awards $67M to ElementUSA, Colorado School of Mines for rare earth processing plant
The U.S. Department of Energy (DOE) awarded $67 million to ElementUSA and the Colorado School of Mines to build a rare earth processing plant in Louisiana. The facility will extract critical minerals from bauxite residue (red mud), a waste product from aluminum production, with the potential to become one of the world's only depleting bauxite residue waste resources for rare earths. This investment aims to reduce U.S. reliance on Chinese rare earth imports and strengthen domestic supply chains for defense, clean energy, and electronics.
The U.S. Department of Energy (DOE) has awarded $67 million to ElementUSA and the Colorado School of Mines to develop a state-of-the-art rare earth processing plant in Louisiana. This project marks a significant step in the United States' efforts to secure a domestic supply of rare earth elements (REEs), which are critical for defense technologies, electric vehicle motors, wind turbines, and advanced electronics. The facility will process bauxite residue, commonly known as red mud, a waste byproduct from aluminum production. Historically, red mud has been stored in massive tailings ponds, creating environmental hazards, but this new plant aims to transform that waste into a valuable resource.
According to ElementUSA, the plant has the potential to make the Louisiana residue one of the only depleting bauxite residue waste resources in the world for rare earth extraction. Currently, global rare earth production is heavily dominated by China, which controls roughly 60% of global mining and over 90% of processing capacity. This dependency poses a significant strategic vulnerability for the United States, especially as demand for rare earths skyrockets due to the clean energy transition. The DOE grant, funded through the Bipartisan Infrastructure Law, underscores the U.S. government's commitment to building a resilient domestic critical minerals supply chain.
The Colorado School of Mines will provide research expertise, particularly in developing efficient, low-cost extraction and separation technologies. Traditional rare earth processing often involves harsh chemicals and high energy consumption, but the university team aims to pioneer greener methods that reduce environmental impact. ElementUSA, a company focused on extracting critical minerals from industrial waste streams, will oversee plant construction and operations. The facility is expected to produce separated rare earth oxides, including neodymium, praseodymium, dysprosium, and terbium—all essential for permanent magnets used in electric vehicles and military systems.
Industry analysts see this project as a potential game-changer for the North American rare earth supply chain. By repurposing bauxite residue, the plant addresses two challenges simultaneously: reducing environmental liabilities from existing waste ponds and creating a new domestic source of critical materials. The plant’s location in Louisiana also offers logistical advantages, with access to Gulf Coast ports and existing industrial infrastructure.
However, the timeline for production remains uncertain. ElementUSA has indicated that construction could take two to three years, with full commercial output projected by 2028. Moreover, scaling up from pilot to commercial production in rare earth processing has historically been fraught with technical and financial hurdles. Critics note that while the DOE grant is substantial, ElementUSA will likely need additional private investment to achieve its targets.
Even with these challenges, the $67 million award signals a clear policy shift. The U.S. is no longer solely reliant on China for rare earths, and projects like this, along with Mountain Pass in California and new initiatives in Canada, are gradually building a Western hemisphere supply chain. If successful, the Louisiana plant could serve as a blueprint for extracting rare earths from other industrial waste streams, such as phosphogypsum and coal ash, further diversifying supply. For now, the rare earth market watches closely—this waste-to-resource innovation could reshape both the minerals and waste management industries.
