The physical appearance quality of cathode copper produced by a copper system of a company in Northwest Chi-na has been plagued by rough crystal surface and serious granulation.In response to this problem,many times the technical research,although the yield has been improved,but did not completely solve the problem of unstable product quality.In this experiment,the physical and chemical mechanism of copper electrolyte deep purification,precise solid-liquid separa-tion of solid impurities,additive composition and concentration optimization was developed to solve the problem of quality instability in copper electrolytic production.
