Abstract:The stability of copper cathode quality is related to the stability of enterprise brand image and the successful completion of production tasks. Obtaining cathode copper with flat surface, dense crystal, qualified chemical composition and good physical appearance has always been the key work of electrolytic workshop of Guixi Smelter to improve process technology level. Through a comprehensive analysis of the factors affecting the surface quality of cathode copper, a series of deficiencies in the production process of copper cathode electrolysis brought about by material index control, circulation system production environment and product output washing quality in the production process of cathode copper electrolysis were deeply tracked, and the key technical measures for the control of cathode copper surface quality defects were summarized to further guarantee the improvement of cathode copper electrolysis production quality.
