Environmentally safe promoter for use in flotation

Air is introduced and dispersed throughout the slurry. As the individual air bubbles travel to the surface of the flotation cells, they selectively attach to the collector chemical and associated mineral. The froth formed at the surface of the flotation cell is quickly removed, effectively removing a selective mineral captured within the froth.
