摘　　要：为高效开发利用河南某易泥化矽卡岩型钼矿资源,通过矿石性质研究,确定采用粗细分级分别粗选—粗精矿合并精选的工艺流程。试验结果表明:在给矿钼品位为0.127%的条件下,采用粗细分级分选的工艺流程,得到了钼品位达46.88%、钼回收率为69.70%的硫化钼粗精矿;同时为选矿处理易泥化或含泥量较大的钼矿选择处理工艺提供了参考借鉴。For the effective development and utilization of a sliming skarn molybdenum resources, classification,coarse and fine particles separation respectively,rough concentrate mixed and then endur-ing cleaning flotation process was conducted by the ore property research.Experimental results show that under the condition of raw ore with molybdenum grade of 0.127%,molybdenum sulfide rough concen-trate with molybdenum grade of 46.88% and recovery of 69.70% was obtained through separation by si-zes.And the results can provide references for molybdenum separation process selection on sliming or more silt content molybdenum ores.
