BURLINGTON, Mass. — Advanced materials enterprise Phoenix Tailings has finalized preliminary engineering designs for its commercial-scale rare earth separation facility, marking a critical leap forward in efforts to construct an independent, domestic supply chain for critical elements integral to modern industry and national defense.
The milestone directly accelerates the company’s broader $1.2 billion capital undertaking, known as the Freedom project, which integrates commercial separation and metallization processes. By securing the capacity to both isolate individual rare earth oxides and refine them into end-use metals, the Massachusetts-based company aims to alleviate long-standing vulnerabilities caused by foreign reliance—most notably on Chinese processors who have historically commanded near-monopolistic control over the global market.
Once built, the commercial separation infrastructure is slated to process in excess of 18,000 tons of diversified rare earth feedstocks per year. From this volume, the facility is designed to yield more than 4,400 tons of individual, high-purity separated rare earth oxides, which will in turn feed directly into the company’s commercial metallization systems.
For years, policymakers, defense planners, and industrial leaders across the United States and allied nations have cautioned that domestic supply chains remain dangerously exposed at the midstream refining tier. While several allied initiatives have succeeded in extracting raw ores or gathering secondary materials such as end-of-life electronic waste, the intermediate processing steps needed to convert raw minerals into usable chemical compounds and structural metals have remained concentrated abroad.
Phoenix Tailings’ leadership pointed to these long-standing market vulnerabilities in announcing the engineering advancement, arguing that meaningful technological sovereignty cannot exist without native midstream refining capacity.
“America’s future cannot depend on permission from Beijing,” said Nick Myers, co-founder and chief executive officer of Phoenix Tailings. “Our current metallization operations in New Hampshire have already started giving America an edge. With this advancement by our team and partners, we show that through innovative technology, the United States can fight back and control its own destiny.”
The technical scope of the project centers on closing what materials scientists and industrial economists often refer to as the "Missing Midstream." In standard rare earth supply frameworks, mined rock, mineral concentrates, and recovered e-waste cannot be integrated directly into commercial applications such as electric vehicle motors, wind turbines, avionics, guidance systems, or industrial robotics.
Instead, upstream materials must first undergo separation—a notoriously difficult chemical process that splits intertwined lanthanide elements into distinct, pure rare earth oxides. Following separation, these chemical oxides must undergo metallization, a secondary industrial stage wherein oxides are reduced to pure metals or functional alloys.
Because domestic facilities capable of executing both stages at commercial scale have been largely absent from the American industrial landscape, Western supply chains have frequently been forced to extract minerals domestically, ship raw concentrates overseas for separation and reduction, and subsequently re-import finished compounds and metals at high cost and geopolitical risk.
By mastering and deploying commercial-scale separation alongside its established metallization line, Phoenix Tailings is establishing an integrated operation that bridges these disparate links under a unified domestic umbrella.
The planned separation facilities will leverage a modular architectural approach developed and vetted through intensive technical trials. According to company executives, the core architecture is the culmination of two years of dedicated pilot testing, bolstered by extensive validation procedures conducted in collaboration with specialized third-party engineering partners.
Tomas Villalon, chief technology officer and co-founder of Phoenix Tailings, emphasized that versatility in raw material sourcing was central to the engineering team’s design specifications.
“Our next step is to scale separation to initially process more than 18,000 tons of rare earth feedstocks annually and produce more than 4,400 tons of separated oxides to supply our commercial metal operations,” Villalon stated. “Backed by two years of pilot testing and validation from our engineering partners, the system is designed to handle feedstocks from both mines and recyclers, with a modular design that allows us to expand as feedstock supply grows and keep pace with market demand.”
The modularity of the separation setup allows Phoenix Tailings to adjust its operational footprint and intake capacity iteratively. Rather than committing to a rigid, monolithic refinery design that can take a decade to construct and calibrate, modular processing segments can be deployed, optimized, and duplicated in response to market demand shifts and changing raw material streams.
Furthermore, the dual-feedstock flexibility of the facility accommodates both primary extracted mineral concentrates from conventional mining ventures and secondary streams gathered from recyclers, including spent electronics and retired industrial magnets. This multi-stream compatibility mitigates reliance on any single mine or geographical deposit, giving the processing infrastructure resilient operational continuity regardless of individual upstream bottlenecks.
The realization of the separation engineering milestone also brings the broader Freedom project closer to commercial fruition. Capital requirements for heavy industrial and chemical processing projects of this magnitude are significant, demanding substantial balance sheet strength alongside state-of-the-art technological capability.
To that end, the Freedom initiative received major structural support earlier in the year through a conditional loan commitment extended by the Department of War’s Office of Strategic Capital, announced in June. The public-sector backing reflects the growing imperative within national defense apparatuses to safeguard domestic manufacturing lines from global supply disruptions, export restrictions, and geopolitical blockades.
Advanced defense systems—ranging from precision munitions and radar installations to jet engine components and communication arrays—rely heavily on specialty rare earth metals like neodymium, praseodymium, dysprosium, and terbium. Without continuous, verifiable access to separated oxides and reduced metals, defense logistics remain susceptible to international trade embargoes.
Phoenix Tailings’ current metallization base in New Hampshire has already functioned as a practical proof point for the enterprise, producing refined metals and verifying that domestic processing can adhere to strict commercial and environmental standards. The integration of full separation capacity will allow the company to feed its New Hampshire furnaces directly with domestically refined oxides, establishing a fully closed-loop processing chain.
As global economies pursue broader electrification and industrial modernization, demand for high-performance permanent magnets and allied rare earth compounds is projected to climb steadily over the coming decades. With preliminary design work concluded and key technical validations secured, Phoenix Tailings is turning its focus toward execution and fabrication.
The transition from pilot-validated design to full commercial construction represents an ambitious phase for the company and its project partners. By working toward an industrial baseline capable of refining tens of thousands of tons of complex feedstocks on American soil, the enterprise aims to construct an enduring framework capable of supplying the foundational materials required for Western economic resilience, advanced manufacturing, and long-term national security.
