摘　　要：采用XRD和光谱分析确定了含钼石煤中钼的主要物相。将石煤粉碎过0.074mm筛,添加碳酸钠造球,氧化焙烧,然后用水作为浸出剂浸出钼,考查了焙烧温度、焙烧时间和球团粒径对钼浸出率的影响。结果表明,最佳焙烧温度为650℃、焙烧时间为3h、球团粒径大小为5～15mm,在该条件下,钼浸出率可达96.32%。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.
