Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation

During the flotation process, frothers help create the ideal hydrodynamic conditions such as bubble size and gas holdup required within the pulp in the flotation cell. They generate froth that is stable enough to hold collected minerals on top of the pulp, mobile enough for removal, and decays quickly to assist with downstream operations.

The most widely accepted method for upgrading ultrafine coal is froth flotation. Froth flotation is a physicochemical process that separates particles based on differences in surface wettability. Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles Fig. 17. A chemical reagent, called a frother, is normally added to promote the formation of small bubbles.
