Energy Fuels Inc. has announced a significant advancement in the U.S. rare earth supply chain with the successful production and qualification of high-purity dysprosium oxide at its White Mesa Mill in Utah. The company's dysprosium oxide, which achieved 99.9% purity, has passed initial quality assurance tests by a major South Korean automotive manufacturer for use in permanent magnets. Energy Fuels is the first U.S. company to have both "light" and "heavy" rare earth elements qualified for use in permanent magnet applications, a key milestone for national defense and industrial supply chains. The company plans to expand production to include terbium and potentially samarium oxides, with commercial-scale output of heavy rare earths expected as soon as the fourth quarter of 2026.
