摘　　要：旋流-静态微泡浮选柱在山东某金矿进行分选时在与浮选机尾矿接近的情况下,精矿品位比浮选机高12.69g/t,通过对2种浮选产品的筛分分析,认为浮选柱对微细粒的分选体现出了比较高的选择性和比较强的回收能力,浮选机在粗粒的回收上具有一定的优势,是造成浮选柱精矿品位明显高于浮选机而两者尾矿品位接近的分选结果的原因。The grade of the gold concentrate from separation by cyclonic-static microbubble fl otation column was 12.69g/t higher than that by fl otator in a gold mine in Shandong,while the gold grade of the tailings were almost the same.The sieving analysis of the two kinds of concentrate showed that the separation of fi ne particles by the fl otation column had higher selectivity and stronger recovery,while the fl otator had advantage in recovery of coarse particles,which led to the above experimental results.
