摘　　要：本文结合生产实际初步探讨了电解精炼中阴极铜结粒原因是由阳极板质量（物理外观、化学质量）、始极片的质量及加工制作、电流密度不均、添加剂加入量及配比、电解液中悬浮物含量偏高等原因导致,根据结粒特征进而分析原因,提出预防和消除结粒,实现阴极铜质量长期稳定的生产。This paper discussed in combination with the production practice in the electrolytic refining quality of cathode copper knot grain of reason is that the anode plate （ the physical appearance, chemical quality） quality and processing production, starting, uneven current density, and ratio for the amount of additives, the high suspended solids content in electrolyte causes, according to the characters of grain and analysis the reason, put forward to prevent and eliminate grain, achieve long-term stable quality of cathode copper production. Key Words： electrolytic refining; the anode ; starting sheet; the electrolyte ; additive; grain; copper cathode
