摘　　要：在磷矿浮选过程中会引入大量无机离子,这些离子会对浮选产生一定的影响。研究碳酸盐型胶磷矿反浮选体系中常见无机离子对胶磷矿和白云石浮选行为的影响,探究矿物表面由于离子吸附而引起的表面转化。结果表明,Ca^(2+)、Mg^(2+)、Fe^(3+)、Al^(3+)、PO_(4)^(3-)随着浓度的提高对矿物的浮选起抑制作用,SO_(4)^(2-)和F^(-)在低浓度时对矿物的浮选没有明显影响,在较高浓度时对矿物的浮选有一定的促进作用;矿物经过回水调浆后,X射线光电子能谱仪在矿物表面检测到新的元素吸收峰,说明在浮选体系中存在表面转化现象。In the flotation process of phosphate rock,a large number of inorganic ions are introduced,which can have a certain impact on flotation.The influence of common inorganic ions on the flotation behavior of collophane and dolomite in the carbonate type collophane reverse flotation system is studied,as well as the surface conversion caused by ion adsorption on the mineral surface is explored.The results show that Ca^(2+),Mg^(2+),Fe^(3+),Al^(3+)and PO_(4)^(3-)has an inhibitory effect on mineral flotation with increasing concentration.SO_(4)^(2-)and F^(-)has no significant effect on mineral flotation at low concentrations,but has a certain promoting effect at high concentrations;After the mineral is treated with return water,new elemental absorption peaks are detected on the mineral surface through X-ray photoelectron spectrometer,indicating the existence of surface conversion phenomenon in the flotation system.
