对萤石、方解石和白钨矿进行了单矿物和实际矿石浮选试验，并通过红外光谱和Zeta电位研究了矿物与捕收剂TAB-3和调整剂水玻璃的作用机理。结果表明：用Na2CO3调介质pH 为8～11时，有利于白钨矿与方解石的浮选分离；用NaOH 调介质pH≥11时，有利于白钨矿与萤石的浮选分离。捕收剂TAB-3在白钨矿、萤石和方解石表面均发生化学吸附，但加入水玻璃后，捕收剂TAB-3在萤石和方解石表面的吸附减弱。因此，添加水玻璃有利于白钨矿与萤石的浮选分离，更有利于白钨矿与方解石的浮选分离。

A flotation test on mono-minerals and practical ore of fluorite,calcite and scheelite was conducted.The mechanism of the minerals and TAB-3 collector,sodium silicate regulator was studied by infrared spectrum and Zeta potential.The results showed that it was conducive to a flotation separation of scheelite and calcite when the medium pH was adjusted as 8-11 by use of Na2CO3 .It was conducive to a flotation separation of scheelite and fluorite when the medium was pH≥11 with NaOH.The role between collector TAB-3 and scheelite,fluorite and calcite is chemical adsorption.The collector adsorbed on the surface of fluorite and calcite reduced after adding sodium silicate.Therefore,it is advantageous to the flotation separation of scheelite and fluorite if adding sodium silicate duing their flotation separation,and more advantageous to the flotation separation of scheelite and calcite.
