近年来从海底锰结核中综合回收钴镍铜锰等有价金属,对钴锰分离进行了一系列的研究,其中包括氧化沉淀、氨络合物法、硫化沉淀法及应用各种萃取剂的萃取分离方法。上述各种方法,化学分离方法虽然简 In recent years, comprehensive recovery of valuable metals such as cobalt, nickel, copper and manganese from seafloor manganese nodules has carried out a series of researches on the separation of cobalt and manganese, including the methods of oxidative precipitation, ammonia complexation, sulfidation precipitation and the application of various extractants Extraction separation method. The above methods, although the chemical separation method is simple
