Phoenix Tailings, operator of one of the few domestic rare earth processing plants, is installing equipment at a larger site in Exeter to enhance production capabilities.[1] This development underscores ongoing efforts to build out U.S. rare earth metallization independent of foreign supply chains.
Facility Upgrade Underway
The Exeter facility, focused on converting rare earth oxides into metals and alloys, is scaling operations through new installations. Recent coverage highlights this activity as part of broader national initiatives to secure critical minerals.[2] The plant processes diverse feedstocks including mining tailings and recycled materials using electrochemical methods that minimize waste and emissions.
In a March 18 overview, the facility's initial capacity stands at 200 tons annually of light and heavy rare earth metals, with plans to exceed 1,000 tons to meet U.S. defense needs.[3] Company technology enables production of neodymium-praseodymium and dysprosium-iron alloys without reliance on Chinese inputs.
"Phoenix Tailings is the leading rare earth production company, with differentiated technology and a clear path to scaled production," said Clara Andreoletti, CEO of Eni Next.
These upgrades position the facility to expand output of additional elements like samarium and yttrium. Near-term implications include strengthened local contributions to domestic supply chains, with potential for further investment and partnerships in critical minerals processing.
