一、金川公司采用中和除铁、镍精矿沸腾除铜、氯气氧化除铁三段沉淀的净化方法。由于镍是渣的主要成份,不但降低了主金属镍的直收率,而且增加了其他金属回收的复杂性。尤其是钴,要在专门建立的车间中,经过一个冗长的流程才能回收。我们在用季胺硫氰酸盐分离钴、镍的研究中认识到,这种萃取剂对站有极高的选择性,而几乎不受镍的影响。完全可以用于从镍电解液中分离钴。如果电解 First, Jinchuan companies and in addition to iron, nickel concentrate boiling addition to copper, chlorine oxidation of iron three sections of the purification method. As nickel is the main component of slag, it not only reduces the direct yield of primary nickel but also increases the complexity of other metals recovery. Cobalt, in particular, needs to be recycled in a purpose-built workshop after a lengthy process. In our study of the separation of cobalt and nickel with quaternary ammonium thiocyanate, we realized that this extractant has a very high selectivity to the station with little effect from nickel. It can be used to separate cobalt from nickel electrolyte. If electrolyzed
