Phoenix Tailings
Phoenix Tailings is a clean mining and metals production company that focuses on extracting rare earth and critical metals from mining waste, known as tailings. The company utilizes a proprietary, non-toxic, and carbon-neutral process to transform waste slurry left after ore processing into valuable metals. Founded by a team of experienced professionals, including entrepreneur Nicholas Myers and MIT-trained engineers, Phoenix Tailings aims to create a sustainable domestic supply chain for clean energy technologies and advanced manufacturing. The company has developed innovative technology that addresses the environmental challenges of traditional rare earth mining, which is often energy-intensive and polluting. Phoenix Tailings has built a pilot processing facility and has produced over 50 kilograms of metal, with plans for mass production to significantly contribute to U.S. rare earth metal production. With over $20 million in funding and support from the U.S. Department of Energy, Phoenix Tailings is committed to reducing mining waste pollution and enhancing U.S. strategic independence in critical metals.
