Flotation Process | Encyclopedia.com

flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.

Explain the froth floatation process? - askIITians

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.

Froth Flotation | Definition of Froth Flotation by Merriam ...

Froth flotation definition is - flotation in which air bubbles are introduced into a mixture of finely divided ore or other material with water and a chemical that aids attachment of the bubbles to the particles of the desired material and its recovery as a froth.

Explaining the Process of Froth Flotation

These collect in a froth heavily laden with sulphide particles. The gangue particles are not brought up by the bubbles, but remain in the mass of the pulp. This is the so-called froth flotation. Its variations, acid-froth, agitation- froth, and pneumatic-froth processes are discussed in detail later.

Froth floatation - SlideShare

Jun 16, 2013· Froth floatation 1. Froth FloatationPresented By:Gulfam Hussain 2. Introduction Floatation is an extractive process where variousminerals can be selectively extracted. Flotation is a selective process and can be used toachieve specific separations from complex ores. For example, in poly-metal ores such as Pb-Zn-Cu, floatation allows separate extraction of Pb, Cuand Zn.
