  • 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.
