| 摘 要： | 依据白钨矿矿石性质，采用一次磨细的单一浮选流程，在Ｎａ２ＣＯ３碱性介质中用改性Ｎａ２Ｓｉｏ３和改性脂肪酸进行白钨矿粗选，采用水玻璃＋ＹＮ进行白钨加温精选，小型试验和工业试验均获得良好的指标。在原矿含ＷＯ３１．４５％的工业试验中，获得白钨精矿品位６８．１９％，回收率８２．１６％。

| Abstract: | On the basis of study on the ore property of scheelite, a single flotation flowsheet with fine grinding at one stage is adopted, the roughing of scheelite is carried out with a modified Na\-2SiO\-3 and modified fatty acid in an alkaline (Na\-2CO\-3) medium, the scheelite rougher concentrate is then cleaned with an agent, YN and water glass at elevated temperature. Good results have been achieved in both lab test and commercial test. A commercial test on a raw ore containing 1\^45% of WO\-3 resulted in a scheelite concentrate with the grade of 68\^19% and the recovery of 82\^16%. |
