Two main reasons can be responsible for the most effective flotation of fluorite (Fig. 3) at its zero point charge pH value. The first one is ensuring the maximum hydrophobicity of mineral surface owing to both zero charge of the surface (that is its unpolar state) and chemisorbed collector with hydrocarbon chains directed towards solution.

Fluorite is a strategically important mineral. Commercial deposits of fluorite are widespread throughout the world and its availability is essential to industry.1 The method of concentrating fluorite depends on the final application. Whereas a metallurgical-grade fluorite is obtained by gravity and magnetic separation methods, flotation is the major concentration process for the production of ...

Froth flotation, also called ore flotation when used in mining applications, is a method for physically separating particles by having air bubbles that selectively adhere to specific surfaces. The particles with attached air bubbles are carried to the surface and removed. Froth flotation is one of the most widely used methods for ore beneficiation.
