    06/04/2020· In ore/mineral beneficiation, froth flotation is a method by which commercially important minerals are separated from impurities and other minerals by collecting them on the surface of a froth layer Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out This method of froth floatation is a method of mineral processing inFlotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineralFroth flotation | ore dressing | BritannicaThis article is cited by 30 publications Mark Ma Enhancement of Hematite Flocculation in the Hematite–Starch–(LowMolecularWeight) Poly(acrylic acid) SystemFroth Flotation of Iron Ores Adsorption of Starch
