摘　　要：硅酸钠是一种常见的抑制剂,常被用来抑制石英、方解石及硅酸盐类脉石。在白钨矿精选过程中,硅酸钠常与其它药剂一起组合使用,作为含钙脉石的选择性抑制剂。为解释硅酸钠在白钨矿精选过程中对含钙脉石的抑制机理,在浮选试验的基础下,采用红外光谱的手段,详细分析了白钨矿、方解石、萤石与硅酸钠作用前后,三种单矿物表面特征峰吸收带的波数位置变化情况,从机理研究的角度验证了浮选试验的准确性。Sodium silicate is a common inhibitor, often used to inhibit quartz, calcite and silicate gangue. As a selective inhibitor of calcium gangue, in the scheelite cleaning flotaton process, sodium silicate is often used in combination with other reagents. In order to explain the inhibition mechanism of sodium silicate by scheelite cleaning flotaton process based flotation test and infrared spectroscopy analysis , the position change of surface characteristics of the peak absorption band with the wave number with and without sodium silicate of the three single minerals , scheelite, calcite and fluorite, verified the accuracy of the flotation test from the an-gle of mechanism.
