Principles of Froth Flotation with Photos Minerallurgy
Apr 25, 2021· Froth flotation utilises the differences in physico-chemical surface properties of the particles to be separated, especially differences in hydrophobicity. Bubbles rise through a heterogeneous solid-liquid suspension, accumulating certain of the solid particles, which attach by virtue of their hydrophobicity.

Jun 08, 2016· The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.

Froth flotation is an important concentration process that selectively separates hydrophobic valuable minerals from hydrophilic waste gangue. In its simplest form, froth flotation is a method where minerals can be “skimmed” from the surface of “slurry” that is “foamed” with the assistance of specific chemicals, water, and air bubbles.
