| 简介 |
Disclosed is a method for recovering rare earth elements and transition metals whereby rare earth elements and transition metals are efficiently separated from an RE-TM-based mixture, which comprises compounds and/or a mixture containing rare earth elements and transition metals including Fe, to thereby conveniently and economically recover recycled materials having high purity, comprising : a loading step for loading an RE-TM-based mixture in a graphite crucible; a separation step for heating the graphite crucible containing the RE-TM-based mixture loaded therein to separate the RE-TM-based mixture into an oxide phase comprising the rare earth elements as the major components and a metal phase containing the transition metals, and to melt the RE-TM-based mixture; and a recovery step for separating the RE-TM-based mixture into oxides comprising the rare earth elements as the major components and metals or alloys containing the transition metals, and separately recovering the same. |
