Froth flotation - Wikipedia
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

floatation mineral processing - paviljoen7
Flotation. Background. Froth flotation is the follow-on operation, after comminution and classification, in the process of liberating and separating minerals by exploiting the differences in physical properties of the different minerals that make up an ore. Froth flotation is achieved when particles are separated based on their surface potential.

Flotation | Article about flotation by The Free Dictionary
Flotation works best for separating particles with sizes 0.1-0.04 mm. Finer particles separate less well, and particles smaller than 5 microns impair the flotation of larger particles. The detrimental action of micron-sized particles is diminished by specific reagents.

Different types of separation methods for minerals
Separation occurs when the minerals are soaked in a chemical solution, causing the materials to aggregate based on whether they are hydrophobic (water-repellant) or hydrophilic (water-attracting). Froth flotation uses large amounts of water laced with chemical agents, most of which is unrecyclable.
