    Froth flotation is an important concentration process that selectively separates hydrophobic valuable minerals from hydrophilic waste gangue. In its simplest form, froth flotation is a method where minerals can be "skimmed" from the surface of "slurry" that is "foamed" with the assistance of specific chemicals, water, and air bubbles.
