Phoenix Tailings Launches Rare Earth Refinery in New Hampshire to Enhance Domestic Supply Chain
Phoenix Tailings has developed a technology platform to produce rare earth metals domestically from mining waste without hazardous chemicals. The company opened a metallurgy facility in Exeter, New Hampshire, to process 200 tons per year of light and heavy rare earth metals, with plans to scale up to over 1,000 tons. The initiative addresses supply chain vulnerabilities due to China's dominance in the rare earth market, particularly in refining and separation. Recent investments include a $76 million Series B round and $40.2 million in strategic capital.

Phoenix Tailings, co-founded by MIT alumni, aims to produce rare earth metals domestically using a proprietary electrochemical system that minimizes waste and emissions. The company opened a facility in Exeter, New Hampshire, capable of processing 200 tons annually of light and heavy rare earth metals, with plans to scale to over 1,000 tons.
This facility represents a significant step in reducing dependence on Chinese supply chains, where China controls 91% of global refining output. In 2025, Phoenix Tailings secured $76 million in Series B funding and an additional $40.2 million in early 2026 to accelerate production. The facility processes materials from various unconventional sources, promoting a circular economy model.
