| Abstract: |
| The main mineral phase of molybdenum in molybdenum bearing stone coal was confirmed with XRD and spectral analysis. Stone coal was crushed to pass 0.074 mm screen and pelletized with sodium carbonate, and then the pellet was oxidizing roasted and leached by water to recover molybdenum. The effects of roasting temperature and time, diameter of pellet on molybdenum leaching rate were investigated. The results show that the leaching rate of molybdenum is 96.32% under the optimum conditions including roasting temperature of 650 ℃, roasting time of 3 h, and diameter of pellet of 5~15 mm. |
