Copper is a non-ferrous metal closely related to human activities,widely used in electrical engineering,light industry,machinery manufacturing,construction,and defense sectors.This study systematically analyzes the factors affecting cathode copper quality,including anode plate physical specifications and composition,cathode plate quality,electrolyte composition,electrolyte circulation system volume,organic additive dosage,electrolyte temperature,cell loading quality,and short circuit handling at the cell surface.Through years of refined management and optimized control processes,the quality of cathode copper has been continuously improved.The first-pass rate of cathode copper increased from 88.16 % in 2017 to 95.51 % in 2020,and the final yield of reworked cathode copper reached 99.88 %,significantly enhancing the quality of cathode copper to meet high-purity standards and substantially boosting the brand image of Zijin Copper.
