摘　　要：研究了用溶剂萃取法从氯化铜溶液中去除钴。结果表明 ,当水相 pH控制在 3.7～ 4.0时 ,铜、钴和钙、钴的分离系数可达 2 0～ 30 ,能够满足铜、钙被同时除去的要求。提出了改进金川有色金属公司P2 0 4萃取工艺、降低生产过程中产出的氯化铜溶液中的钴浓度的设想。通过调整P2 0 4萃取工艺参数 ,利用金川公司提供的钴渣浸出除铁后液 ,经过实验室累计 2 0 0h的联动扩大试验 ,取得了令人满意的结果。试验产出的氯化铜溶液体积小 ,钴质量浓度低于 0 .5g/L ,[Cu]/ [Co]>6 0 ,其它杂质浓度也达到了要求的指标。Removal of cobalt from copper chloride solution by solvent extraction with P204 is studied.The separation coefficient of copper and cobalt,calcium and cobalt are all in 20～30 while pH of aqueous phase is between 3.7～4.0.Copper and calcium can be removed at same time.A good results,content of cobalt is 0.5 g/L,/>60 and content of other impurities can meet technical demands in copper chloride solution,have been acquired by controlling process parameters during 200 hours bench-scale experiment in laboratory.The ideas of improving extracton process for reducing cobalt content in copper chloride solution are proposed.
