| Abstract: |
| Mechanism of oxygen pressure leaching for nickel sulfide concentrates was analyzed. The effects of leaching temperature, pressure, initial acidity and time on leaching were investigated. The results show that nickel leaching rate is 98% above under the conditions including reaction temperature of 110 ℃, initial acidity of 80 g/L, pressure of 0.8 MPa, and reaction time of 4 h. |
