摘　　要：以氯化钾、明胶和硫脲为基础添加剂,复配聚丙烯酰胺、十二烷基苯磺酸钠、糖精和添加剂A中的一种或几种制得一系列复合添加剂,研究其对交直流叠加电解精炼铜的影响,并对复合添加剂的作用机理进行简单探讨。结果表明:自制复合添加剂均能不同程度的改善阴极铜质量,添加剂Ⅷ(含硫脲5 mg/L、聚丙烯酰胺10 mg/L和添加剂A 0.6 mL/L)和Ⅹ(含氯化钾10 mg/L、硫脲5 mg/L、明胶6 mg/L和添加剂A 0.6 mL/L)是两种作用效果较好的复合添加剂,可以明显改善阴极铜质量,有望成为未来铜电解精炼工艺中的新型复合添加剂。The compound additives are made up of potassium chloride,gelatin,thiourea and one or two of polyacrylamide,saccharin,sodium dodecylbenzene sulfonate and additive A.The effect of these new compound additives on copper electrorefining by AC/DC electrolysis has been discussed.The results show that： all the selfmade additives can improve the quality of cathode copper to varying degrees.when the additives Ⅷ（including thiourea 5mg/L、polyacrylamide10mg/L and additive A 0.6 mL/L）and Ⅹ（including potassium chloride 10 mg/L、thiourea 5 mg/L、gelatin 6mg/L and additive A 0.6 mL/L）exist,a better cathode copper can be got,and they are promised to become the new compound additives in the future.
