| 摘 要： | 内蒙某含砷钼矿中砷主要以毒砂形态存在。用煤油作捕收剂,辉钼矿有良好的可浮性。在浮选过程中毒砂进入钼精矿中,导致钼精矿含砷高。本次试验在钼矿浮选工艺条件试验中,着重对毒砂抑制剂进行了对比试验。试验结果表明:采用Ca(ClO)2与Na2SO3组合抑制剂、结合阶段磨矿阶段选别的工艺,获得砷含量为0.20%、钼品位为46.55%的钼精矿。

| Abstract: | The arsenic of the arsenic-bearing molybdenum ore in Inner Mongolia mainly exists in the form of arsenopyrite.If kerosene is adopted as collector,the molybdenum has good flotability.But in the course of flotation the arsenopyrite was into the molybdenum concentrate,which led to containing high arsenic.In this experiment,the comparison experiment of different inhibitors for arsenopyrite was emphasized.The result showed that the molybdenum concentrate containing 0.20% of arsenic was obtained with the grade of molybdenum as 46.55% by adopting the combined inhibitor of Ca(ClO)2 and Na2SO3 and the technology of stage grinding and stage separating. |
