【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WO₃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。更多还原

【Abstract】 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 and76.17%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.更多还原
