Several types of chemicals are involved in froth flotation, and several more can be involved. First is the promoter or frother. This chemical simply creates bubbles of sufficient strength to make it to the surface without breaking.

Frothers are very important reagents playing a multiple role in flotation of particulate matter. The frothers facilitate formation of either foam or froth and favourably modify the structure of films between bubbles as well as solid …

I don't have deep knowledge in this area, but I know that froth flotation is an important waste water treatment step used in a variety of industries.

cesses that preceded froth flotation, generally the separation was aided by levitation of the oil/mineral mass, either through the entrainment of air during mixing or by reduction of pressure to generate bubbles, or by the addition of sulfuric acid to generate carbon dioxide bubbles from carbonate minerals in the ore.

Froth flotation is an important concentration process that selectively separates hydrophobic valuable minerals from hydrophilic waste gangue. In its simplest form, froth flotation is a method where minerals can be “skimmed” from the surface of “slurry” that is “foamed” with the assistance of specific chemicals, water, and air bubbles.

As the name froth flotation would cause us to expect, an important class of chemical reagents is frothing agents. As is the case with collectors, a wide range of compounds is used, depending on mineral type and operating conditions.

froth layer. Particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.

Barbian et al. (2005) developed a froth stability column to be used at industrial scale, allowing froth stability to be correlated to flotation performance. The results, from a copper sulphide ore, showed that the highest dynamic froth stability resulted in the highest copper grade but lowest recovery.

Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.
