摘　　要：依据矿石的工艺矿物学研究,对低品位细脉型黑、白钨矿石提出了粗粒重选—细粒浮选的工艺,在原矿含WO30.23%、Mo0.018%的情况下,获得了重选钨精矿含钨WO363.54%、钨回收率70.11%,细泥浮选钨精矿含钨WO335.22%、钨回收率10.48%,综合钨精矿含钨WO357.53%、钨回收率80.59%,钼粗精矿含钼2.31%、钼回收率50.54%的结果,钨和钼得到了有效回收。According to the study of minerals process, the processes of gravity concentration for coarse particles and flotation for fine are put forward for low grade veinlet tungsten ores. Under the conditions of WO3 and Mo are 0.23% and 0.018% respectively in crude ores, the gravity tungsten concentration is got which the content of WO3 is 63.54%, the recovery of W is 71.11%, and the flotation tungsten concentrtion is got which the content of WO3 is 35.22%, the recovery of W is 10.48%, the WO3 is 57.53% in comprehensive tungsten concentration, the recovery of W is 80.59%, Mo content is 2.31% in Mo coarse concentrate, the recovery of Mo is 50.54%. W and Mo are recovered effectively.
