摘　　要：研究了常温常压下,采用SO2浸出-离子浮选-溶剂萃取工艺从钴土矿中综合提取钴、锰、铜、镍等有价金属。结果表明,锰回收率大于97%,钴总回收率大于95%,镍总回收率大于90%。Under normal temperature and pressure, a hydrometallurgical process is presented for extracting cobalt,manganese,copper and nickel from earthy cobalt by reduced leaching with SO2-ion flotation-P507 solvent extraction. The results show that total process recovery is up to 97% for Mn, 95% for Co and 90% for Ni.
