It is the fluorosilicic ion that exsits in the slurry and plays an important role in flotation, fluorosilicic ion not only reacted with Fe〓 on the surface of aegirine to form ionic compound, but also formed stable Si-F bond in Si-O etching reaction. Only ionic compound was obtained when it was attached to hematite surface according to the theories of coordination chemistry, Compared with SiF〓, Fatty acid ion preferentially acts with Fe〓 on the minerals surface, therefore, SiF〓 Can't obstruct the adsorption of collector on the surface of hematite completly, but can reduce the flotation recovery of aegirine selectively.

运用FTIR、XPS等测试方法仔细研究了氟硅酸盐抑制剂对含铁硅酸盐钠辉石的选择性抑制作用机理,氟硅酸盐在弱酸性条件下对赤铁矿浮选的抑制作用很微弱,而对含铁硅酸盐钠辉石强烈抑制,从而扩大了两者之间的浮选差异;SiF〓是矿浆中起抑制作用的主要成分,SiF〓不仅与钠辉石表面的Fe〓形成离子型配合物,而且还与Si-O键形成稳定的Si-F共价键,而与赤铁矿表面只能形成离子型配合物,根据晶体配位场理论,与SiF〓相比较羧酸根离子将优先与矿物表面Fe〓发生配位作用,因此SiF〓的存在并不能完全阻碍捕收剂在赤铁矿表面的吸附作用,却能够选择性地抑制钠辉石的上浮。
