摘　　要：探讨了回收废弃MH/Ni电池正极工艺条件。利用化学沉淀法实现镍钴较彻底的分离,从中回收得到的碳酸镍和硫酸钴产品,纯度在99.0％以上,回收率超过98.0％。本工艺有望获得较好的经济效益和良好的社会效益。A process was developed for the recovery of discarded MH/Ni battery positive electrode materials. The cobalt and nickel were separated completely by chemical precipitation. Recovery of nickel carbonate and cobalt sulphate were more than 98.0% and the purities were over 99.0%. The process was promising to have a preferable economic benefit and a good social benefit.
