In this study, the activation mechanisms of fluorite inhibited using Na 2 SiO 3 by adjusting the solution pH to neutral and slightly alkaline conditions were investigated. The solution chemistry of sodium silicate and microflotation tests showed that SiO(OH) 3 − in the Na 2 SiO 3 solution strongly inhibited fluorite flotation, while H 4 SiO 4 and SiO …

Fluorite. Fluorite [CaF2] is a common accessory mineral in many hydrothermal ore deposits, and its dissolution can release F. The dissolution of some layered silicates, such as biotite, can also release F. Fluorite is the least soluble F-containing mineral that might be expected to form and limit F concentrations in low temperature systems.

Fluorite is commercially named fluorspar composed of calcium fluoride (CaF2). It is the principal source of fluorine. The same is used in production of hydrofluoric acid, which is used in a wide variety of industrial applications including glass etching. Fluorite tends to occur in well-formed isometric crystals, forming cubes and octahedrons.
