Froth flotation is a separation process by which particles are selectively attached to air bubbles. It is one of the most dynamically complex industrial processes in use today.
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.

Figure 17: Illustration of the “release analysis” method for determining the maximum grade of material that can be produced by a froth flotation process. Each stage of flotation removes more of the entrained and poorly floatable particles from the froth, until the final froth product consists only of the most strongly-floatable material.
