本文研究了氯化浸出含镍物料所得的含钴铁量高的镍溶液的净化和钴铁回收工艺，采用Ｎ＿（２３５）－异辛醇－煤油萃取体系在离心萃取器中分离镍与钴、铜、铁、锌，用离子交换除铅，用活性碳除有机物，得到可用于生产１号标准电镍的氯化镍溶液以及含Ｃｏ大于１００ｇ／Ｌ，Ｃｏ／Ｎｉ大于４０００的氯化钻溶液和含Ｆｅ大于２５ｇ／Ｌ，Ｆｅ／Ｎｉ大于１０００的氯化铁溶液，镍、钴回收率分别大于９９％和９７％。 In this paper, the purification of nickel solution containing cobalt iron with high content of cobalt and the recovery of cobalt-iron from the leaching of nickel-containing materials by chlorination were studied. Nickel and cobalt were separated from the centrifugal extractor by N_ (235) -iso-octanol-kerosene extraction system, Copper, iron, zinc, with lead ion exchange, with activated carbon in addition to organic matter, can be used for the production of nickel standard No. 1 nickel chloride solution and Co containing more than 100g / L, Co / Ni greater than 4000 drilling solution of diamond And ferric chloride solution containing more than 25g / L of Fe and more than 1000 of Fe / Ni. The recoveries of nickel and cobalt are more than 99% and 97% respectively.
