Froth flotation - Wikipedia

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.

Of the more specialised reagents, the largest volume chemicals are flocculants and coagulants, flotation frothers and sulphide mineral collectors. The most specialised high value reagents, although of lower volume, are solvent extractants.
