Surface Chemistry of Froth Flotation (2^nd Ed., 2nd ed. 2004) Volume 1: Fundamentals

The second edition of the book Surface Chemistry ofFroth Flotation by Dr. S.R. Rao presents many significant advancesof the 20 years since the publication of the first edition, includingelectrochemistry of sulfide flotation, use of chelating compounds inflotation, mechanism of activation and depression, inadvertentactivation, fine particle flotation and several others of currentinterest to flotation engineers, researchers and graduate students.Dr. Rao has gathered recent published information and integrated itwith established knowledge under various topics. The book alsodescribes areas of ongoing research in the subject. The process of froth flotation - an outstanding example of appliedsurface chemistry - is extensively used in the mining, metallurgicaland chemical industries for separation of particulate matter,especially for selective concentration of individual minerals. Surface Chemistry of Froth Flotation is written mainly forgraduate students and researchers in the field of flotation. Inaddition, those in mineral processing, metallurgy, surface and colloidscience, and recycling of materials will also find material ofinterest. In Volume 1, the fundamentals of surface chemistry together withprinciples of ionic equilibria and electrochemistry that are relevantto the understanding and control of the flotation process areexplained. Volume 2 describes flotation reagents and their chemistry andreviews the mechanism of their action in flotation. They includecollectors, activators, depressants, frothers and complexing agents.Numerous references to the literature are included.
