Abstract:On the basis of system analysis, through a series of technical modifications such as adding electrodeposition tank to remove copper, increasing purification and impurity removal capacity, and pumping the purification final solution to the anode sludge after acid leaching treatment, the balance of copper, impurities and acid in the electrolytic system was finally realized. The quality of cathode copper was guaranteed. The direct copper yield was improved. The production cost was reduced. At the same time, the cost of wastewater treatment in the final solution of copper removal and sulfuric acid consumption in the process of acid leaching of anode mud were reduced, and the benefit was maximized, which has important reference significance to the same industry.
