摘要
阴极铜中银含量达10 g/t以上时,一方面会造成银经济损失,另一方面阴极铜中的银往往属于有害杂质,对下游铜深加工带来不利影响。通过对电解生产情况的分析,优化调整电解液Cl;、添加剂配比、电流密度、电解液温度,可有效控制阴极铜银含量至8 g/t以下,平均含量降至6.86 g/t,按照年产阴极铜30万t计,每年可挽回经济损失360万元。
When silver content in cathode copper is more than 10 g/t, it will causes loss of silver, and bring adversely affects on downstream copper deep processing because silver in cathode copper is often a harmful impurity.Silver content in cathode copper can be effectively controlled below 8 g/t, and average silver content in cathode copper can be reduced to 6.86 g/t through analysis of electrolytic production and adjustment of production process, such as optimization and adjustment of Cl;content in electrolyte, additive ratio, current density, and electrolyte temperature.According to annual output of cathode copper of 300 kt, the annual economic loss can be saved 3.60 million yuan.
