| 摘 要： | 含钼矿物的氧化与溶解是提高含钼黑色页岩的中钼浸出率的关键所在。首先进行了含钼矿物氧化碱浸基础理论分析,绘制了钼浓度-pH热力学优势图,并在此基础上开展实验研究。试验结果表明:在转化温度为150℃,反应时间3 h,搅拌转速500 r/min,釜内氧压为1.2 MPa,矿浆液固比2∶1的条件下,不同pH值浸出体系中钼的浸出率变化趋势与lg[Mo]T-pH图中钼总溶解量一致。

| Abstract: | Oxidation and dissolution of Mo-bearing minerals are key factors to enhance the Mo leaching rate from Mo-bearing black shale.The paper analyzes the theory of oxidative alkaline leaching of Mo-bearing black shale and draws molybdenum concentration-pH figure,based on which,several experiment are completed.The experimental results show that the leaching rate of molybdenum under the different pH of the leaching system of Mo-bearing black shale was consistent with the lgT-pH diagram under the condition of temperature 150℃,reacting time 3 hours,agitator rotating 500 r/min and oxygen pressure of 1.2MPa. |

| Keywords: | Mo-bearing black shale hydrometallurgy leaching leaching rate |
