METHOD FOR RECOVERING SAMARIUM AND COBALT FROM SAMARIUM-COBALT BASED ALLOY

摘要

PROBLEM TO BE SOLVED: To provide a method for recovering samarium and cobalt from a samarium-cobalt based alloy having satisfactory treatability.SOLUTION: A samarium-cobalt based alloy is heat-treated in the coexistence of a boron oxide BO, thus samarium in the samarium-cobalt based alloy is concentrated into the boron oxide so as to be separated, and cobalt in the samarium-cobalt based alloy is recovered as a cobalt-boron based alloy.
