Energy-efficient process delivers rare-earth element for magnets

Neodymium is a rare-earth element essential for producing the strongest permanent magnets, which are widespread in defense technologies, hard drives, medical imaging devices, electric vehicle motors, wind turbines and more. Despite its designation in the U.S. as a critical material, neodymium is primarily mined and refined overseas. China controls much of the supply chain, and the country recently threatened to expand restrictions on the exports of rare earth elements.
