Recovery of lithium from spodumene-bearing pegmatites: A …
DMS and froth flotation are the most widely accepted of all beneficiation techniques across the world. While DMS is suitable for coarsely liberated pegmatites, primarily used as a pre-concentration step, flotation is an efficient unit to recover the finely liberated spodumene not only from the ores but also from the pre-concentrated products.

Froth flotation of fluorite: A review
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]].

Froth flotation and its modeling aspects
Flotation is an important physicochemical process of particle separation, which is based on differences in the surface property of the minerals. It is a key unit operation for the beneficiation of minerals from the ore deposits that show fine liberation characteristics. Flotation has been in vogue for more than 100 years now.
