RESEARCH ON EXTRACTING COBALT FROM THE COMPLEX COPPER AND COBALT ORE WITH LOW SULFUR BY PRESSURE LEACHING PROCESS

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.
