摘    要：对国内某大型铜钼矿浮选厂的铜钼混合精矿进行了分离浮选试验研究。在分离前对精矿进行强化脱药,采用组合抑制剂YF851和YF212进行分段抑制,可显著改善铜钼分离效果,获得了较好试验指标:钼精矿品位为49.91%、含铜0.69%,钼回收率为84.45%;铜精矿品位为32.90%,含钼0.07%,铜回收率为99.98%。

Abstract: Experimental researches on separate floatation of mixed concentrate are carried out in a large copper-molybdenum mine.Intensive agent removal is put into practice before the separation,and the combination depressor of YF851 and YF212 can improve the separation of copper and molybdenum for its depression effect in different stages.Finally,the grade of molybdenum concentrate is 49.91 % and the recovery rate of molybdenum is 84.45 %,containing 0.69 % copper;the grade of copper concentrate is 32.90 % and the recovery rate of copper is 99.98 %,containing 0.07 % molybdenum.
