摘　　要：矿物表面的物理化学性质由矿物颗粒在溶液中的化学行为决定,矿物在溶液中的溶解组分又决定了矿物在浮选体系中的行为状态。因此,矿物溶液化学的研究可以解释大多数溶解度较高的盐类矿物在浮选中与各类捕收剂的作用机理。为了预测和控制选矿药剂在不同p H值条件下对白钨矿、方解石、萤石浮选行为的影响,对三种主要含钙矿物在水溶液中的溶液反应及反应常数进行了研究,以确定合理的浮选环境、药剂制度,实现从理论角度分析并解决常温条件下白钨矿难以分选的难题。Chemical behavior of mineral particles in solution determines physical and chemical properties of mineral surfaces, the minerals dissolved components in the solution in turn determine behavior and state of mineral flotation system. Therefore, studying on mineral solution chemistry can explained the mechanism of high solubility mineral salts by flotation with various types of collectors. In order to predict and control the flotation behavior of scheelite, calcite and fluorite under different pH, research on the reaction in aqueous solution and the reaction con- stant with the three calcium-bearing minerals were carried out for determining reasonable reagent regime and flota- tion environment. The theoretical analysis can help to resolve the difficult problems of separating scheelite from cal- cite and fluorite under normal temperature.
