Currently, the raw materials for producing rare earth elements are their chloride and fluoride. Molten salt electrolysis Industrial mass production on mixtures of rare earth metals generally employs the molten salt electrolysis method. Meanwhile, the electrolysis process includes two methods chloride electrolysis and oxide electrolysis.
Notably, approximately 40% of mined rare earth production is reduced to metals and alloys, including most of neodymium (Nd), samarium (Sm), and dysprosium (Dy), for applications such as neodymium metal for Nd-Fe-B permanent magnets, samarium metal for Sm-Co permanent magnets, lanthanum (La), cerium (Ce), praseodymium (Pr), and neodymium (Nd) for
Oct 11, 2021 Low-grade sources of rare earth elements (REE), for example from industrial waste, typically contain many rare earth elements and other metals mixed together. A new extraction and separation method relies on a protein called lanmodulin (LanM) that first binds to all the rare earth elements in the source. Then other metals are drained and removed.
May 18, 2021 Rare earth elements are widely distributed throughout the earths crust, but generally in low concentrations.
