摘　　要：考察了铜电解精炼过程中银的走向,并通过调整添加剂配方以降低阴极铜中Ag含量。结果显示,铜电解过程中0.84%的Ag进入阴极铜中,按20 g/t_(Cu)加入添加剂A,产出的阴极铜物理外观质量良好,银含量降至10 g/t以下,达到A级铜国家标准。The distribution of Ag in the copper electrolytic refining process was investigated,and Ag content in the cathode copper was reduced by adjusting additive agents. It is found that 0.84% of Ag is pulled into cathode copper in the process of copper electrolysis. The experiment with the addition of additive A at the amount of 20 g/t_(Cu) resulted in the cathode copper with Ag content lower than 10 g/t,conforming to national standard.
