Refining processing of copper electrolysis

The effect of electrolytic temperature,current density and concentration of copper-ion on the surface quality of copper on cathode was investigated.The cathode was characterized by visual inspection and metallographic method.The optimum parameters for laboratory test were determined as follows: electrolytic temperature is 50 ℃,current density is 200 A/m2,and concentration of copper-ion is 35～40 g/L.Under optimum conditions,smooth and high-purity cathode copper could be obtained.
