摘　　要：以吉林某低硫铜钴矿为例,采用加压浸出技术,不加入黄铁矿或硫磺,实现反应自热进行,使钴铜镍的浸出率达到98%以上。铁、钙、镁、硅进入渣相,无二氧化硫产生。This paper introduces extracting cobalt from copper-cobalt ore with low sulfur from Jilin province by pressure leaching without adding sulfur and pyrite which could react by autotherm. All of the leaching rates of cobait, copper and nickel are beyond 98%. The iron, calcium, magnesium, silicon would be precipitated into residue and no SO2 emission generated.

关 键 词：低硫铜钴矿 加压浸出 自热反应
