钼铅矿

Thermodynamic analysis was carried out to show the effect of technical conditions on sodium hydroxide decomposition of wulfenite.

利用热力学平衡图对氢氧化钠分解钼酸铅矿的工艺条件进行讨论。

As a result, the processing of wulfenite leaching by sodium hydroxide is carried out. Additionally, feasibility of the processing of wulfenite leaching by sodium hydroxide is proved, but Pb2+ reacts with hydroxyl to form complexes which is leached into solutions. So removing the complexes lead from solution is needed.

通过对Pb-Mo-H2O系的热力学分析，苛性钠分解彩钼铅矿在一定的pH值下是可行的，但在碱分解过程中Pb2+与羟基形成了配合物，主要是以的形式存在而大量进入溶液，因此，尚需进一步除铅。

In the third area, Pb2 is gradually supersaturated in solution with the increase of pH value, so the Pb2 is deposited as sediment. As a result, the processing of wulfenite leaching by sodium hydroxide is carried out. Additionally, feasibility of the processing of wulfenite leaching by sodium hydroxide is proved, but Pb(superscript 2+) reacts with hydroxyl to form complexes which is leached into solutions. So removing the complexes lead from solution is needed.

通过对Pb-Mo-H2O系的热力学分析，苛性钠分解彩钼铅矿在一定的pH值下是可行的，但在碱分解过程中Pb(上标 2+)与羟基形成了配合物，主要是以Pb3的形式存在而大量进入溶液，因此，尚需进一步除铅。

Na2S-leaching process,microbe-leaching process and mechanochemistry directly leaching process were introduced and compared,the result showed that Mo leaching ratio could reach 99% by mechanochemistry directly leaching process for wulfenite,in which process energy consumption was the lowest,and least equipment was needed,the newly developed process was the best way to recover Mo from wulfenite.

硫化钠浸出工艺、生物浸出工艺、机械化学直接浸出工艺三种工艺的比较结果显示，机械化学直接浸出工艺具有能耗低、设备少、钼浸出率高等优点，是处理钼铅矿的最理想的方法，钼的浸出率可达到99%以上。
