The process for production of cathode copper using zinc hydrometallurgy purification residue was studied.The technological conditions of leaching zinc with dilute sulfuric acid,oxidation leaching of copper and insoluble anode electrowinning copper were investigated.The experimental results show that the leaching rate of zinc,cadmium and cobalt are 98.69%,96.15% and 70.70%,respectively under the optimum conditions.The direct recovery rate of copper in electrowinning system is 80.69%,the recovery rate of copp...
