  • Froth flotation

    In the froth flotation process gangue particles are separated from the values (often mineral ores or coal) by virtue of differences in hydrophobicity; the more hydrophilic gangue resides in the interstitial liquid where it drains downwards whereas the more hydrophobic values rise with the bubbles into the concentrate stream.
