- Froth Flotation Material Separation
Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while the particles that remain completely wetted stay in the liquid phase.

At present, the primary beneficiation approach of fluorite is flotation [5].In the deposits, fluorite is often associated with gangue minerals such as calcite and quartz, which share similar surface properties with fluorite (i.e. solubility, crystal structure, hydrophobicity, and zeta potential), making the effective separation challenging to achieve [[6], [7], [8]].
