Description
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 to flotation engineers, researchers and graduate students. Dr. Rao has gathered recent published information and integrated it with established knowledge under various topics. The book also describes areas of ongoing research in the subject. The process of froth flotation - an outstanding example of applied surface chemistry - is extensively used in the mining, metallurgical and chemical industries for separation of particulate matter, especially for selective concentration of individual minerals. Surface Chemistry of Froth Flotation is written mainly for graduate students and researchers in the field of flotation. In addition, those in mineral processing, metallurgy, surface and colloid science, and recycling of materials will also find material of interest. In Volume 1, the fundamentals of surface chemistry together with principles of ionic equilibria and electrochemistry that are relevant to the understanding and control of the flotation process are explained. Volume 2 describes flotation reagents and their chemistry and reviews the mechanism of their action in flotation. They include collectors, activators, depressants, frothers and complexing agents. Numerous references to the literature are included.
