摘　　要：江西某低品位白钨矿,由于含有大量可浮性与白钨矿极为相近的钙、铝离子脉石矿物,浮选分离极其困难。试验在工艺矿物学研究的基础上,对其采用硫化矿浮选-白钨粗选-白钨常温精选-白钨加温精选的选矿工艺对其进行了浮选探索性试验研究,小型闭路试验获得钨精矿品位WO_350.23%、回收率71.26%的选别指标,有效地实现了该低品位白钨矿的浮选分离。A low-grade scheelite in Jiangxi province is extremely difficult to be separtated because it contains a largeamount of calcium and aluminum ion gangue minerals that are highly buoyant with scheelite. A flotation exploratoryexperiment was performed on the scheelite by the flow sheet of ＂sulphide ore flotation-scheelite roughing-scheelitefine dressing at room temperature-scheelite dressing at heated temperature＂. A small-scaled closed-circuit testobtains tungsten concentrate grade WO3 50.23 %, with the recovery rate of 71.26 %. The low-grade scheelite flotation separation was effectively achieved.
