Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, stone 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.

Flotation Principles Mineral Processing & Metallurgy

Flotation, in its latest phase, is a process of concentrating ores by frothing. When crushed ore, previously mixed with water and a relatively minute addition of oil, is agitated violently in the presence of air, a froth is formed. This froth, rising to the surface of the liquid mixture, is laden with sulphides or other metallic particles, while the earthy material, or gangue, subsides to the

1 Froth Flotation Fundamental Principles

1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while the particles that remain completely wetted stay

Flotation Fundamentals Mineral Processing & Metallurgy

The basic principles of surface chemistry have been applied extensively to the understanding of flotation phenomena. While some success has been achieved in fundamental studies, it generally is not yet possible to quantitatively predict industrial scale flotation performance very well from first principles. This problem is not surprising in light of the complex nature of flotation, involving

The basic purpose of the collector is to select form a hydrophobic layer on a given mineral surface in the flotation pulp and thus provide conditions for attachment of the hydrophobic particles to air bubbles and recovery of such particles in the froth product. Frothers are heteropolar surface-active compounds that lower the surface tension of water and have the ability to adsorb on the air
