ABSTRACT:
A process is disclosed for recovering zinc from a material containing zinc sulfide. The zinc sulfide-containing material is chlorinated in an aqueous medium to form zinc chloride and elemental sulfur. A water-immiscible solvent (preferably inert) for the sulfur is added to the aqueous chlorinating solution during the chlorination process. The aqueous solution which contains zinc values is separated from the water-immiscible solvent containing sulfur. The zinc values can be recovered from the aqueous layer.
