| Abstract: |
| The article introduces extracting cobalt from copper-cobalt ore with low sulfur by pressure leaching without to add sulfur and pyrite which could autothermal react. All of the leaching rates for cobalt, copper, nickel are beyond 98%. The iron, calcium, magnesium, silicon would be precipitated into residue and no SO2 emission. |
