氟硅酸铵在赤铁矿与含铁硅酸盐浮选分离中的选择性抑制作用

Selective Depressive Action of Ammonium Hexafluorosilicate in Flotation Separation of Hematite and Iron-containing Silicate

纯矿物浮选试验结果表明，在pH4～5的弱酸性条件下，氟硅酸铵对赤铁矿浮选的影响较小，而对霓石强烈抑制，从而能够实现两种矿物的浮选分离。

The results of single minerals flotation test showed that at pH 4 ~ 5 representing a weakly acidic condition , ammoniun fluorosilicate had little effect on hematite flotation but could strongly depress aegirite , realizing a separation of the two minerals by flotation .
