旋流-静态微泡浮选柱用于铜钼分离的试验研究

利用旋流—静态微泡浮选柱半工业分选试验系统对某选矿厂铜精矿产品进行了铜钼分离的试验研究。经过浮选柱粗选—粗精矿再磨—三段柱精选的闭路流程,在入料钼品位0.17%的情况下,可以得到钼精矿品位47.51%、钼回收率72.07%的浮选指标,铜回收率达到99.99%。该流程工艺简单,在基本不损失铜金属的情况下,得到了合格的钼精矿产品,实现了资源的综合回收利用。

EXPERIMENTAL STUDY ON THE COPPER-MOLYBDENUM SEPARATION BY USING CYCLONIC-STATIC MICRO BUBBLE FLOTATION COLUMN

Object of this study was the copper concentrate of some concentrating mill,experimental study on copper-molybdenum separation was made in the semi-industrial system of cyclonic-static micro bubble flotation column.Using closed cycle flowsheet of column rougher flotation——grinding rough concentrate again——three column cleanings,from the copper concentrate containing Mo of 0.17%,the test got the molybdenum concentrates containing Mo of 47.51% and recovery rate of 72.07%,the copper recovery rate was 99.99%.This flowsheet was simple,in the condition of little loss of the copper concentrate,the up to grade molybdenum concentrates were produced,the goal of resources comprehensive utilization was achieved.
