Al impurity, the floatabilities of hematite and aegirine were resemble, which is contributed to the existence of structrual iron ion on surfaces of both minerals. It is the structrual iron ion that accelerates the floatability of aegirine greatly and leads to difficult separation with hematite. 2. The basic mechanism of actions of fluorosilicate salts as selective depressants of aegirine during the direct flotation of hematite was investaged detaily by using FTIR and XPS spectrocppy, fluorosilicate salts are poor depressants for hematite, but are very strong depressants for iron-containing silicate such as aegrine in weakly acid medium, which can enlarge the flotation differences between two minerals.

运用X射线衍射、俄歇能谱等测试手段研究了赤铁矿与钠辉石纯矿物的晶体结构特征，表面破裂面的元素组成与赋存状态，发现在白云鄂博不同的矿床（氧化矿段，原生矿段，风化矿段）存在着三种颜色与可浮性均有所差别的钠辉石，其可浮性的差异主要是由于表面含铁量及Ca、Al等杂质含量的不同而引起的，结构Fe〓的存在导致钠辉石可浮性剧增从而与赤铁矿难以分离。
