| Abstract: |
| A novel process to extract cobalt and copper from copper sulphide ore and heterogenite in Congo (Kinshasa) by combination leaching was put forward. The results show that leaching rate of Co and Cu is 98.80% and 96.01% respectively under the optimum conditions including mass ratio of copper sulphide ore to heterogenite of 0.4, initial concentration of sulfuric acid of 5 mol/L, L/S of 5∶1 mL/g, reaction temperature of 80 ℃, and reaction time of 5 h. |
