摘　　要：钴土矿还原浸出， 浸出液中和除铁， 中和液用亚硝酸钴钾法沉淀钴并焙解得到氧化钴。钴的总回收率９４－３９ ％ 。A process with reduction leaching to asbolite ore, neutralization of leached solution to remove ferric ions, precipitation of cobalt from neutralized solution with potassium cobaltintrite, and roasting decomposition of precipitates to produce cobatous oxide has been developed. The total recovery of cobalt reaches 94 39%.
