摘　　要：河南栾川三道庄某低品位钨钼矿WO_(3)品位为0.1%左右,钨主要以白钨矿形式存在,由于钨的嵌布粒度较细,脉石矿物种类多,性质复杂,钨回收难度较高。针对该低品位矿进行钨回收试验,在钨粗选阶段采用聚糖类有机抑制剂LM替代水玻璃,采用捕收性和选择性相对较好的捕收剂ZF,并在钨精选阶段采用低模数水玻璃,减少了抑制剂消耗,最终从WO_(3)品位0.097%的给矿中获得了WO_(3)品位31.22%、回收率82.84%的钨精矿,实现了该低品位钨资源的高效浮选回收。A low-grade tungsten-molybdenum ore in Sandaozhuang,Luanchuan,Henan contains about 0.1%WO_(3).Tungsten mainly exists in the form of scheelite.Due to the fine grain size of tungsten,the variety and complex properties of gangue minerals,it is difficult to recover tungsten.The tungsten recovery test was carried out for the low-grade ore.The polysaccharide organic inhibitor LM was used to replace the sodium silicatein the tungsten roughing separation,and the collector ZF with relatively good collecting and selectivity was used.The low modulus sodium silicate was used in the tungsten cleaning,which reduced the consumption of the inhibitor.Finally,the tungsten concentrate with WO_(3)grade of 31.22%and recovery rate of 82.84%was obtained from the feed ore with WO_(3)grade of 0.097%,which realized the efficient flotation recovery of the low-grade tungsten resource.
