ABSTRACT Hydrometallurgical process for the recovery of copper arsenate from zinc plant cement copper cake residues and the use thereof in the purification of zinc electrolyte, with the attendant upgrading of the copper value in the treated cement copper residues. The cake residues are first subjected to an acid leach followed by an alkali addi?ion to adjust the pH of the slurry to about 3.5 to 4.0 and to extract zinc, cadmium and cobalt in solution and provide a copper-enriched residue. Cobalt is then precipitated and separated from the extraction solution. The copper-enriched residue is subjected to caustic leach to extract arsenic in solution therefrom and provide a copper-enriched cement copper cake product. The arsenic containing extraction solution is then reacted with a copper salt to form copper arsenate residue and leave purified zinc electrolyte.
