    The second edition of the book Surface Chemistry of Froth Flotation by Dr. S.R. Rao presents many significant advances of the 20 years since the publication of the first edition, including electrochemistry of sulfide flotation, use of chelating compounds in flotation, mechanism of activation and depression, inadvertent activation, fine particle flotation and several others of current interest Froth Flotation: A Century of Innovation comprehensively describes the state-of-the-art research and practice in mineral froth flotation as known and practiced a century after its introduction. Recognized experts from around the world provide in-depth coverage on the historical aspects of flotation; flotation fundamentals; flotation chemistry; flotation cells, modeling, and simulation; and ?hl=id&id=8zpjAhBViC0C.

    The process of froth flotation is an outstanding example of applied surface chemistry. It is extensively used in the mining, mineral, metallurgical, and chemical industries for separation and selective concentration of individual minerals and other solids. Substances so concentrated serve as  › Chemistry › Physical Chemistry. As an important indicator of flotation performance, froth texture is believed to be related to operational condition in sulphur flotation process. A novel fault detection method based on froth texture unit distribution (TUD) is proposed to recognize the fault condition of sulphur flotation in real time. The froth texture unit number is calculated based on texture spectrum, and the probability

Their hydrophile-lipophile properties must be properly balanced and for most good frothers the HLB values are close to 6. This allows them to co-operate actively with the adsorbed collector in the moment of particle-to-bubble ://
