摘要： A method for recovering at least one rare earth element from a phosphor is presented. The method includes a halogenation step (a) and a reduction step (b). The phosphor is first halogenated in a molten salt to convert at least one rare earth constituent contained therein to a soluble rare earth halide. Then, the rare earth halide in the molten salt can be reduced, to convert the rare earth halide to a rare earth element in its elemental state. A method for individually recovering multiple rare earth elements from a phosphor is also presented.
