叙述了从湿法炼锌净液过程中产出的黄酸钴渣中回收氧化钴的方法。介绍了从低品位钴原料(Co0.4％～1.5％)中制取精制氧化钴的工艺流程,以及在生产实践的基础上,对工艺的改进。
A method for recovering cobalt oxide from the cobalt yellow residue produced during the wet refining of zinc is described. The process of preparing refined cobalt oxide from low grade cobalt raw material (Co0.4% ~ 1.5%) is introduced, and the improvement of the process is also given based on the production practice.
