2006-2-7 · Metallurgy is the art, science and technology of turning metals and alloys (i.e., materials consisting of two or more metals) into forms suitable for practical use. Metals make up a large portion of the Earth''s crust (courtesy Alcan Aluminum Ltd). Electrolysis is the key process in refining many metals.

James McClelland, in Treatise on Process Metallurgy: Industrial Processes, 2014. 126.96.36.199.2.2.1 Froth Flotation. The froth flotation process is more than a century old and was developed over a long period of time . It takes advantage of the surface chemistry of fine particles—if one particle''s surface is hydrophobic and another is ...
The flotation process involves crushing the ore to liberate separate grains of the various valuable minerals and gangue components, pulping the ore particles with water, and then selectively rendering hydrophobic the surface of the mineral of interest. A stream of air bubbles is then passed through the pulp; the bubbles attach to and levitate ...
Flotation is a technique, widely used by the mining industry, for the separation of minerals, phosphates, or coal from gangue. Coal and minerals particle size and surface hydrophobicity are two main parameters that affect three key steps in froth flotation process: particle–bubble collision, adhesion, and detachment.

Flotation is an incredibly robust and versatile process that is well accepted around the world. It works equally well on mixed sulfide, oxide, silicate and other ores. It relies on generating a population of bubbles of suitable size that can carry the hydrophobic target mineral (usually but not exclusively sulfide minerals) up to be recovered.
