Froth Flotation Cells - Coal Beneficiation - Parnaby Cyclones

Fine coal can be separated from shale and other waste by the process of froth flotation. The coal is made water repellent by the addition of a reagent such as oil, so that when a suspension of coal is agitated with air it sticks to the air bubbles and floats to the surface, collecting as froth.

Dissolved air flotation - Wikipedia

A very similar process known as induced gas flotation is also used for wastewater treatment. Froth flotation is commonly used in the processing of mineral ores. In the oil industry, dissolved gas flotation (DGF) units do not use air as the flotation medium due to the explosion risk. Nitrogen gas is used instead to create the bubbles.
