Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper 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.

The rising swarms of fine air bubbles, generated by a gas sparger installed at the bottom, carry valuable mineral particles to froth at the top of the column. The distinct design features different from conventional flotation are: (1) addition of wash water at the top of froth, (2) absence of mechanical agitator, and (3) bubble generation .
