FLOTATION

Flotation is a process in Liquid-Solid Separation technology whereby solids in suspension are recovered by their attachment to gas (usually air) bubbles, usually with objective of removing the solids from the liquid. The particles most effectively removed are in the size range from 10 to 200 μm.

Interfacial Chemistry of Particulate Flotation

Techniques based on the tendency of various species to associate with surfactants are: ion flotation for the separation of ions, micro flotation and ultraflotation for very fme particulates, and froth flotation for the separation of min- erals that possess mostly polar surfaces.

Froth Flotation Process - Mineral Processing Metallurgy

Jan 20, 2021  The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.
