Abstract

A method of producing metal chlorides is disclosed in which chlorine gas is introduced into liquid Cd. CdCl2 salt is floating on the liquid Cd and as more liquid CdCl2 is formed it separates from the liquid Cd metal and dissolves in the salt. The salt with the CdCl2 dissolved therein contacts a metal which reacts with CdCl2 to form a metal chloride, forming a mixture of metal chloride and CdCl2. After separation of bulk Cd from the salt, by gravitational means, the metal chloride is obtained by distillation which removes CdCl2 and any Cd dissolved in the metal chloride.
