摘要:
铜是一种与人类关系十分密切的有色金属，广泛应用于电气、轻工、机械制造、建筑、国防等领域。对阳极板物理规格及成分、阴极板质量、电解液成分、电解液循环系统体积、有机添加剂添加量、电解液温度、装槽质量及槽面短路处理等影响阴极铜质量的因素进行了系统分析。经过多年精细化管理和优化控制工艺，不断提升阴极铜质量,阴极铜一次合格率从2017年88.16 %上升至2020年95.51 %，经过修整后的阴极铜最终一次合格率高达99.88 %，阴极铜质量得到大幅提升，达到高纯阴极铜标准，显著提升了“紫铜牌”阴极铜品牌形象。

Abstract:
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.
