Abstract:This paper introduces that the market has made further requirements on the appearance of electrolytic cathode copper obtained from complex materials by conventional method: the labeling rate of cathode copper should be controlled at about 6.24%. By classifying complex anodes and and overcoming the difficulties, optimizing equipment functions and improving fine management of electrolysis, not only the problem of increasing cathode copper labeling rate caused by complex anodes is relieved, but also the quality of cathode copper is improved.
