Technique for Separating Rare Earth Elements from R-Fe-B Magnets by Carbothermal Reduction Method

Carbothermal reduction technique was applied to extract rare earth elements from the machined powders of R-Fe-B based magnets, where R is Nd, Pr, Dy etc., generated as waste from the manufacturing process. After the oxidizing process to oxidize the powders and the reduction process to reduce iron ox...
