Most commercial units are very similar, although some variations exist in terms of cell geometry and impeller design. Industrial flotation machines are now available with individual cell volumes of 28.3 m 3 (1000 ft 3) or more. Coal flotation is typically performed in a single stage with no attempt to reprocess the reject or concentrate streams.

Introduction to Mineral Processing or Beneficiation

5.4 Froth Flotation. In terms of daily tonnages of ore that are treated globally, froth flotation is the single most important mineral recovery process. This is driven by its ability to selectively separate minerals. Flotation is considered to be a physico-chemical process.

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating of 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.
