摘　　要：云南文山某选矿厂矿石主要有用矿物为白钨矿,矿石WO3品位为0.28%,白钨矿与脉石矿物的嵌布关系复杂,属难选低品位白钨矿。为开发利用该矿石,对其进行了选矿试验研究。结果表明:在磨矿细度为-0.074 mm含量占82.90%条件下,进行脱硫浮选,再以氢氧化钠为p H调整剂、硅酸钠+硫酸亚铁为脉石组合抑制剂、733为捕收剂经一粗五精三扫流程进行钨矿浮选后,获得了WO3品位为69.87%、回收率为87.34%的钨精矿,可为该矿石资源的开发利用提供技术依据。The major useful mineral in a tungsten ore of Wenshan county of Yunnan is scheelite （WO 3 grade 0.28%）, which embedded in the gangue minerals. Mineral processing experiments were carried out to utilize the low-grade ore. A scheelite concentrate （WO3 grade 69.87%） was obtained with the recovery reaching 87.34%with a combined process of desulfurizing and flotation. Sodium hydroxide was applied as the pH regulator, sodiumsilicate plus ferrous sulfate as combined inhibitor, and 733 as collector. The technology provides favorable technical basis for the development and utilization of the mineral resource.
