电镍含钴废渣提取氧化钴新工艺

摘要

详述了利用电镍含钴废渣，经过硫酸还原溶解，黄钠铁矾法除铁、P-204萃取除杂质和萃取分离钴镍、氟化铵除钙镁、草酸铵沉淀钴、煅烧等步骤，提取氧化钴的新工艺流程及其生产方法。并介绍了采用此新工艺所制氧化钴粉状产品质量及钴镍的回收率(钴的总回收率不低于92%，镍的总回收率不低于95%)等。%The reactiving mechanism,technological process,every step operating methods and the technical economical effect of the new technology for using the cobalt containing waste residues to extract cobalt oxide was described.The quality of the product and the recovery efficiency of cobalt and nickel were also introduced.
