在分选铜钼精矿中用高锰酸钾作为黄铜矿与黄铁矿的抑制剂。与传统方法采用的硫化钠作了对比试验。采用高锰酸钾的工艺流程特点为 (1)在开路中钼的再回收率较一般将中矿给入精选的指标高;(2)铜钼混合精矿的浮选不加黄药,只要在精选中加小量黄药(1.0-2.0克/吨矿石)。
In the sorting of copper and molybdenum concentrate with potassium permanganate as chalcopyrite and pyrite inhibitors. Compared with the traditional method of sodium sulfide for comparison test. The process of using potassium permanganate is characterized by (1) the recovery rate of molybdenum in the open circuit is higher than the general index of medium ore into the selected; (2) copper and molybdenum mixed concentrate flotation without xanthate, Just add a small amount of xanthate in the selection (1.0-2.0 g / t ore).
