Phoenix Tailings awarded $66M Department of Energy grant to accelerate American rare earth processing
What's the deal? Phoenix Tailings, a startup that operates commercial rare earth metallization facilities, has been awarded a $66 million grant from the US Department of EnergyDealroom has a profile for this one. Try Dealroom → (DOE) to build out domestic rare earth separation capabilities. The project will expand the company's operations upstream, creating a more integrated refining platform on American soil. MIT and the University of Minnesota will support the effort with automation, AI-enabled controls, and feedstock characterisation.
Why now? Rare earth separation remains one of the most constrained segments of the global critical minerals supply chain. These materials are essential for defence systems, advanced manufacturing, consumer electronics, and energy technologies — sectors where US policymakers have grown increasingly anxious about dependence on foreign suppliers, particularly China.
By funding domestic processing capacity, the DOE is betting that companies like Phoenix Tailings can help close a strategic gap.
What could go wrong? Rare earth separation is notoriously complex and capital-intensive. Scaling next-generation separation technologies from lab to commercial production has tripped up well-funded efforts before. Processing a broad range of domestic feedstocks — one of the project's stated goals — adds another layer of technical risk.
Government grants also come with milestones and compliance requirements that can slow timelines.
The signal: Phoenix Tailings, classified as a "breakout" stage company on Dealroom, originally built its business around extracting rare earths from mining waste such as bauxite residue — a clever way to sidestep the environmental and permitting hurdles of traditional mining. The $66 million DOE grant now pushes it upstream into separation, edging it closer to a fully integrated domestic supply chain at a moment when US federal spending on critical minerals reshoring is accelerating across multiple agencies and programmes.
