摘　　要：阜康冶炼厂高冰镍的常压浸出液因含浸出渣悬浮物，导致黑镍除钴工序中所产的钴渣含铜、铁量偏高。在新建的钴车间没有除铁设施的条件下，如按常规方法溶解钴渣，Ｐ２０４萃取除杂系统难以正常运行。研究人员用镍、钴、铁的电位－ｐＨ图确定出选择性溶解镍、钴的操作区域及操作方法，获得了合格的镍钴溶解液，使投产顺利进行。At Fukang Smelter,the atmospheric leaching solution of high nickel matte contains suspension of leaching residue,leading to high Fe and Cu content in cobalt residue prodced from the nickel system.There is no neutralizing system for removing Fe at the new cobalt pland.If cobalt residue is dissolved with the conventional method,the extraction system with P204 is difficult to run normally.A standard Ni-Co solution can be obtained by using the potentialpH curve of Ni,Co,Fe to determined the optimum operation zone and method of selection dissolution of Ni and Co.The Ni-Co system is smoothly put into operation.
