Abstract:The relevant process control parameters were obtained through the plant production application of parallel flow electrolysis in Yanggu Xiangguang Copper Industry. The influences of the main parameters such as electrolyte circulation amount, additive dosage, electrolyte temperature and electrolyte composition on the quality of cathode copper in the process of parallel flow copper electrolysis were discussed. The appropriate control parameters in electrolytic production to ensure the quality of cathode copper were determined.
