For example,froth flotationis a technique commonly used in themining industry. In this technique, particles of interest are physically separated from a liquid phase as a result of differences in the ability of air bubbles to selectively adhere to the surface of the particles, based upon their hydrophobicity.

2. Coal flotation. Coal is a major commodity, which is used mainly for two purposes: thermal coal, which is burned to create electrical energy; and metallurgical (coking or steelmaking) coal, that is used in the production of crude steel. Our focus here is on metallurgical coal which is often naturally hydrophobic, and responds well to flotation.

The bubbles should be able to carry the coal to the surface without breaking, and once out of the flotation machine, it should break down. The most commonly used frothers for coal flotation are eitherpure alcohol, e.g.MIBC(methyl isobutyl carbinol) or a mixture of various alcohols and the polypropylene glycol-based frothers.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Columnflotationcells have become increasingly popular in thecoal industrydue to their ability to improveflotationselectivity. The improvement can be largely attributed to the use of froth washing, which minimizes the nonselective entrainment of ultrafine minerals matter into the froth product.
