  • 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.

  • Coal Washing | Density Separation | Froth Flotation | RPM ...

    Low density material is clean coal while high density material is reject rock. Coal washing is accomplished by one of two major processes, by density separation or by froth flotation. Both processes depend on the fact that the particles of which a coal sample are made have different densities.

  • Effect of polyaluminum chloride on coal flotation ...

    1. Introduction. Froth flotation is a particle separation method widely used to upgrade raw coal in fine particle size fraction. Central to this method is to enable air bubbles in water to selectively pick up hydrophobic coal particles, with the formed bubble-particle aggregates rising up to the froth phase to be discharged as product, while the hydrophilic gangue particles are left behind.
