  • Froth flotation Wikipedia

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

  • Froth flotation process The Dow Chemical Company

    Dec 19, 1978· The froth flotation process is applicable to ores containing metallic and nonmetallic mineral values. In flotation processes, it is desirable to recover as much mineral values as possible from the ore while effecting the recovery in a selective manner, that is, without carrying over undesirable portions of the ore in the froth.
