| 摘 要： | 就某地微细粒含量高、易泥化的难选铜矿石，提出部分优先浮选新工艺，即原矿经破碎磨矿后采用高效、节能的微细粒分选设备旋流-静态微泡浮选柱进行分选，直接得到部分最终合格精矿，解决了该铜矿中微细粒级浮选机回收能力差造成金属流失的问题。在最优参数条件下进行了连选试验。研究结果表明，采用该工艺流程可以优先得到铜品位21.46%，回收率30.04%的铜精矿。

| Abstract: | For a refractory copper ore with feature of fine particle and ease-to-slime,a new flow-sheet of partially preferential flotation was proposed,that is,raw ores are separated after crushing and grinding by the high efficiency and energy-saving micro-fine separator with cyclonic-static micro-bubble flotation column to directly get some final qualified concentrate.By this way,the problem of low recovery capacity by micro-fine flotation machine for a copper mine which result in metal loss are resolved.And the pi... |
