Abstract: The removal of copper and iron impurities from leaching solution of NixCoyMnz spent battery material is studied. The copper is removed through replacement by iron powder, while the effects of Fe powder amount, reaction time and reaction temperature on the copper removal and loss of nickel, cobalt and manganese are examined. And the iron is removed by precipitation in the copper removed solution, while the conditions of pH value, reaction time and reaction temperature are discussed, which can influence the iron removal and the loss of nickel, cobalt and manganese. The result shows that Cu and Fe can be removed 99% at least. And at the same time, the loss rates of Ni, Co and Mn are about 2%, 3% and 2%, respectively. The leaching solution after purification accords with the demand of preparation of NixCoyMnz ternary system precursor.

摘要： 对镍钴锰三元废电池材料盐酸浸出液分离去除铜和铁杂质进行了研究. 采用铁粉置换法除铜，考察了铁粉用量、反应温度和反应时间等因素对铜脱除率及镍钴锰损失率的影响；除铜后浸出液采用针铁矿法除铁，考察了反应时间、反应温度及终点pH值对铁去除率和镍钴锰损失率的影响. 结果表明，铜和铁的去除率均在99%以上，镍、钴、锰的总损失率分别为2%, 3%, 2%. 净化后溶液满足制备合格镍钴锰三元系前驱体的要求.
