US rare earth supply efforts are gaining another $134mn in federal support as the Department of Energy backs two demonstration projects designed to recover and refine rare earth materials from domestic waste streams.
US rare earth supply development will focus on projects led by the Colorado School of Mines and Phoenix Tailings. Both groups have been selected for award negotiations under the DOE’s Rare Earth Element Demonstration Facility Program.
US rare earth supply remains constrained by limited domestic separation, refining and metallisation capacity. The latest awards target those midstream gaps rather than simply adding new mining projects.
The projects are also notable because both will use waste-derived feedstock. That could create new rare earth supply without depending entirely on conventional mines.
Louisiana Project Targets Rare Earths From Bauxite Waste
The Colorado School of Mines-led project will develop a demonstration facility near the Gramercy alumina refinery in Louisiana’s St John the Baptist Parish.
The facility will process critical mineral-rich bauxite waste into separated rare earth oxides and then refine those oxides into rare earth metals.
This approach is strategically important because alumina production creates large waste streams that can contain recoverable critical minerals. Extracting rare earths from existing residues could turn an environmental liability into a domestic resource.
The project also connects the aluminium and rare earth value chains. Bauxite is primarily processed for alumina, but recovering additional metals could improve resource efficiency and create new revenue streams.
Colorado School of Mines will work with ElementUSA, Pacific Northwest National Laboratory, Principal Minerals and Rare Earth Technologies.
The project therefore combines academic expertise, national laboratory capability and industrial partners. That structure could help move rare earth recovery technology from laboratory development toward commercial-scale deployment.
Phoenix Tailings Adds Domestic Rare Earth Metal Capacity
Phoenix Tailings will build a separate demonstration-scale facility focused on producing high-purity rare earth metals from waste-derived domestic feedstock.
This is especially important because rare earth metal production remains a major bottleneck in western supply chains. Separated oxides still need to be converted into metals and alloys before they can support permanent magnet manufacturing.
Phoenix Tailings will collaborate with the Massachusetts Institute of Technology on the project.
The company’s focus on waste-derived feedstock also supports a circular supply model. Industrial residues, scrap and other secondary materials can complement mine supply while reducing reliance on imported rare earth inputs.
For the US, the strategic objective is integration. Domestic mining or recycling alone is insufficient unless separation, refining, metallisation and downstream manufacturing are also available.
The DOE funding shows that federal policy is increasingly targeting these missing processing stages. If the projects scale successfully, they could strengthen domestic supply for magnets, defence systems, electronics and advanced manufacturing.
The Metalnomist Commentary
The US is increasingly treating industrial waste as a critical minerals resource. The real value of these projects lies in proving that domestic residues can be converted into separated oxides and high-purity metals at commercial scale.
