Phoenix Tailings

Phoenix Tailings is a US-based rare earth metals company headquartered in Woburn, MA, on a mission to restore American industrial independence by building the domestic refining capacity needed to produce critical metals cleanly and at scale. Founded roughly six years ago (circa 2019), the company extracts and refines rare earth and other critical metals from mining waste (tailings) and other unconventional feedstocks using proprietary electrochemical and advanced materials science processes - entirely without the toxic chemicals or hazardous waste associated with traditional rare earth processing. Their vertically integrated platform spans feedstock sourcing, extraction, separation, metallization, and delivery of finished rare earth metals and alloys to defense, energy, EV, robotics, and advanced manufacturing end users.

Phoenix Tailings operates multiple US facilities: an R&D hub in Woburn, MA, a production facility in Burlington, MA, and a flagship commercial metallization facility in Exeter, NH - the first rare earth metallization facility of its kind in the United States. Their technology rests on three pillars: proprietary chemistry, advanced industrial hardware, and - following their 2026 acquisition of Boston-based Machinery Partner - AI-driven digital infrastructure and automation. This combination allows for continuous production optimization, predictive monitoring, and rapid scaling of rare earth refining systems on American soil.

Phoenix Tailings is strategically critical to the US energy and defense supply chain because China has long dominated rare earth refining - the single most important chokepoint in the critical minerals supply chain. Rare earths are essential inputs for EV motors, wind turbines, missile guidance systems, medical devices, and consumer electronics. By building a fully clean, domestically operated rare earth refining and metallization platform, Phoenix Tailings is directly addressing a critical national security vulnerability, with backing from both private investors and the US Department of Defense (via the Department of War/Army). The company's zero-waste, zero-emissions philosophy further positions it as a sustainable alternative to incumbent Chinese processors.
