摘　　要：在铜电解的精炼以及处理过程中,会分化一些有害的杂质,如果不对其作出合理地去除或者处理,会对最终的应用效果产生极为严重的影响,甚至会危害整个电解分化系统。因此,为了提升整体的阴极铜质量,也为了避免形成较大的经济损失,本文对铜电解精炼过程中杂质物质的脱除方法作出分析与研究。进行铜电解精炼分配比确定,并建立重叠旋流电解结构,在此基础上,采用化学沉淀法实现铜电解精炼中杂质的脱除。最终的实验结果表明:铜电解离子交换脱除法得出的摩尔比相对较高,表明其对于杂质物质的脱除效果较好,具有一定的潜在应用价值。In the refining and treatment process of copper electrolysis,harmful impurities may differentiate.If they are not properly removed or treated,it will have a serious impact on the final application effect and even endanger the entire electrolysis differentiation system.Therefore,in order to improve the overall quality of cathode copper and avoid significant economic losses,this article analyzes and studies the methods for removing impurities in the copper electrolytic refining process.Determine the distribution ratio of copper electrolytic refining and establish an overlapping vortex electrolysis structure.Based on this,the chemical precipitation method is used to remove impurities in copper electrolytic refining.The final experimental results indicate that the molar ratio obtained by the copper electrolysis ion exchange removal method is relatively high,indicating that it has a good removal effect on impurity substances and has certain potential application value.
