Abstract:Since reaching the production standard in 2014, the 300000 tons copper electrdysis system in the electrolytic workshop of a companys smelter had faced the problem of increasing production capacity without increasing equipment and facilities. By improving the operation efficiency, increasing the current density and repairing the stainless steel cathode plate and other process measures. The cathode copper production capacity was increased about 12.6% compared with the design capacity, and good economic benefits were achieved.
