Abstract

Ion flotation is an efficient method to remove or recovery of heavy metals, rare and precious metal ions, and organic pollutants from aqueous solution. The added surfactants served as collectors and frother mainly dominate the indexes of ion flotation. Therefore, the review summarized the surfactants (chemical synthetic surfactants, biosurfactants, and nanoparticle surfactants) used in ion flotation. The advantage, disadvantage, and outlook of the three types of surfactants were also discussed.
