| Abstract: |
| A new technology of acid pressure leaching was developed to treat Ni-Mo ore. The effects of temperature, partial pressure of oxygen, ratio of liquid to solid (L/S), and reaction time on oxidation rate and leaching rate of nickel and molybdenum were studied. The results show that the oxidation rate of molybdenum is over 98.3% and the leaching rate of nickel is 98.7%, under the optimum conditions including L/S=5, partial pressure of oxygen of 0.4 MPa, temperature of 150 ℃, and reaction time of 2 h. |
