【摘要】 从分析Fe³⁺—H₃PO₄—H₂O、Ca²⁺—H₃PO₄—H₂O、Mg²⁺—H₃PO₄—H₂O、Ca²⁺—H₂CO₃—H₃PO₄—H₂O、Mg²⁺—H₂CO₃—H₃PO₄—H₂O、Ca²⁺—H₂CO₃—H₂O、Mg²⁺—H₂CO₃—H₂O、Ca²⁺—Mg²⁺—H₂CO₃—H₂O等体系的热力学平衡出发,以较新的平衡常数,自由能等数据为依据,讨论了溶液—矿物（纯化学组成）的溶解、吸附现象。考虑到空气中CO₂对矿物溶解和吸附特性的影响,提出以“金属离子—络合配体”的方法增大矿物表面性质差异实现胶磷矿和白云石的浮选分离。更多还原

【Abstract】 The dissolution and adsorption properties of minerals, based on thermodynamic equilibria of the system of separation of collophane and dolomite,such as Fc3+-H3PO4-H2O, Ca2+-H3PO4-H2O,Mg2+-H3PO4-H2O, Ca2+-H2CO3-H3PO4-H2O,Mg2+-H2CO3-H3PO4-H2O,Ca2+-H2CO3-H2O,Mg2+-H2CO3-H2O, Ca2+-Mg2+-H2CO3-H2O,have been analysed in light of newer equilibrium constants and free energy data. The effects of CO2 in air on the dissolution and adsorption of minerals have been discussed. As a result ,the method using "metallic ion- chelate" combined regulator to increase the differences of surface properties between two minerals has been put forward to achieve the flotation separation of collo-pnane and dolomite.更多还原
