Earth Mineral Flotation Collectors

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.

Simply said; a Flotation Collectors is a chemical used to make the surface of minerals, which is metallic, hydrophobic or in layman’s term ‘afraid of water’ or ‘water hating’ as others like to say. This chemical used will behaved, in a way, as a wax would when you applied it to your car. After wax (or hydrophobic agent) is adhered to the surface, that surface with see water pearl-away.
