D-9,129 C-3821 METALLOTHERMIC REDUCTION OF RARE EARTH CHLORIDES Abstract of the Disclosure Rare earth chlorides and oxychlorides can be reduced to substantially pure rare earth metals by a novel, high yield, metallothermic process. The rare earth chloride feedstock is dispersed in a vessel containing a suitable molten chloride salt bath and a molten metal collection pool. Enough sodium, potassium and/or calcium is added to the bath to produce a stoichiometric excess of calcium metal with respect to the rare earth. The bath is stirred such that the calcium metal reduces the rare earth feedstock. Stirring is stopped and the reduced rare earth metal is collected in the metal pool in the reaction vessel.
