摘　　要：总结了国内外铜电积的工程实践,对铜电积过程添加剂进行优化。结果表明,铜电积液添加Co2+有利于减缓阳极腐蚀速度和降低阳极电位,合适的Co2+浓度为100mg/L;古尔胶有利于生成表面光滑、平整的阴极铜,适宜用量为每吨铜50g;硫脲在不同的电流密度下对阴极铜质量影响不同;铜电积液不适宜添加盐酸。Engineering practice of copper electrowinning at home and abroad were summarized.Additive was optimized by experiment.The results show that cobalt ion in electrowinning solution is beneficial to decrease anode corrosion rate and anode potential,the optimum cobalt ion concentration is 100mg/L.Gul glue is favor of forming smooth surface cathode copper,the optimum additive is 50 g for one ton copper.Thiourea has different effect on cathode copper under different electric current density.Hydrochloric acid is unsuitable as additive.
