Abstract Group I-B metal halides are recovered from bimetallic salt complexes having the generic formula MIMIIXn?Aromatic wherein MI is a Group I-B metal, MII is a Group III-A metal, X is halogen, n is the sum of the valences of MI and MII, and Aromatic is a monocyclic a- romatic hydrocarbon having 6 to 12 carbon atoms by contacting a solution of the bimetallic salt complex in an aromatic hydrocarbon with anhydrous ammonia. The Group I-B metal halide, which precipitates quantitatively from the solu- tion, is readily separated from the NH3:MII halide complex which remains in solution. This process can be used, for example, to recover anhydrous cuprous chloride from the cuprous aluminum tetrachloride toluene complex.
