摘　　要：某白钨矿WO_(3)含量为0.27%,现场生产钨精矿品位较低,为53.11%,出售计价系数低。为提高钨精矿品位,实验针对矿石的性质特点,优化药剂制度,常温浮选采用组合捕收剂MLP,加温浮选采用辅助抑制剂硫化钠后,可显著提高钨精矿品位至66.18%,回收率基本不变,且抑制剂水玻璃用量显著降低。优化后技术经济效果显著。There are 0.27%WO_(3) in a scheelite Ore.The grade of scheelite concentrate produced on site is 53.11%.Because the grade of the concentrate is low,the pricing coefficient of the concentrate is low.In order to improve the grade of scheelite concentrate,according to the properties of the ore,combined collector was used for flotation at room temperature,sodium sulfide was used as an auxiliary inhibitor at heating flotation.After the flotation reagent is optimized,the grade of scheelite concentrate can be significantly increased to 66.18%,the recovery rate of the concentrate remains basically unchanged,and the dosage of inhibitor sodium silicate is significantly reduced.The technical and economic effects of the optimized process are significantly improved.
