    MINERAL PROCESSING. FROTH FLOTATION. Froth Flotation was initially developed to separate sulfide minerals such as chalcopyrite from gangue. Collectors and frothers are added to a slurry to attach selected minerals to air bubbles to float them to the surface to be collected as a concentrate. Many sulfide and oxide minerals can be floated.
