The raw material of cathode copper producing line is mixed purple copper or coarse copper, it will be made into anode copper plate by smelting of pyrogenic process. After foaming and washing the anode plate, then put into electrolyte flume for electrolyzing refining process. After seven days, it will be cathode copper plate (cathode copper). The quality standard is GB/T467-1997 of China (CU-CATH-2). Electrolyzing in Electrolyte Tank
