Gases affect bubble sizes - Froth Flotation …
There is a particular type of flotation machines that use a plunging jet to shear gas into virtually any bubble size you want simply by modifying the air flow rate and jet velocity. A good example is the Jameson Cell that uses a jet of slurry of about 17 m/s and air to pulp ratio of about 0.6 which is able to generate bubble sizes of 0.3-0.6 mm.

How to Improve Flotation Mineral Processing …
When the mineral particle size is fine, the bubble size can be appropriately reduced, but not too small, otherwise the recovery rate and concentrate quality will be reduced, so as to increase the collision probability between the bubble and the mineral, so as to improve the flotation mineral processing effect.
Froth flotation - Wikipedia
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, stone recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
