Activation mechanisms of sodium silicate-inhibited fluorite in ...
2021.1.15 Fluorite flotation was inhibited by adding sodium silicate under alkaline conditions. By adjusting the pulp pH to 7–7.5, the floatability of sodium silicate-inhibited fluorite was restored, and fewer Na 2 SiO 3 species were adsorbed on fluorite surfaces.

The mechanism of sodium silicate depressing fluorite in
Combined with the flotation and adsorption results, the mechanism of sodium silicate inhibiting fluorite is that sodium silicate will envelop sodium oleate during heating cleaning, resulting in sodium oleate not re-adsorbing on the fluorite surface.
