摘　　要：针对某低品位细脉浸染型钨钼矿石性质,采用"全硫混合浮选—混合精矿再磨—钼硫分离"工艺回收辉钼矿,获得了钼精矿含钼为46.14%,回收率为80.32%;采用"731氧化石蜡皂常温浮选法"回收白钨矿,获得了白钨精矿含WO_3品为67.21%、回收率为76.17%。着重对白钨的常温浮选工艺和加温浮选工艺、水玻璃模数等方面进行了试验研究,得到了较为经济合理的选矿回收工艺,为该矿石的开发利用提供了依据。Flotation experimental study was carried out on a low grade disseminated type tungsten- molybdenum ore. The ＂ total sulfur mixed flotation-mixed concentrate regrinding-molybdenum sulphur separation＂ process was employed to recover molybdenite, then the molybdenum concentrate with 46.14% molybdenum grade and 80.32% recovery was obtained; Through the ＂731 oxidized paraffin wax soap flotation at room temperature＂ process to recover scheelite, the scheelite concentrate with 67.21% WO3 grade and 76.17% recovery was obtained. In this paper, the experiments focus on scheelite flotation at room temperature and heated flotation process flotation process were studied, and a more economical and rational mineral recovery process is obtained, providing a basis for the development and utilization of minerals.
