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 raw materials for producing appropriate metals and chemicals. The importance of flotation in technology is chiefly due to the ease with which it can be made selective and versatile and to the economy of the process. The objective of this book is to review the fundamentals of surface chemistry together with the relevant aspects of organic and inorganic chemistry that-in the opinion of the author-are important ~ control of the froth flotation process. The review updates the information that had been available in books by Sutherland and Wark (1955), Gaudin (1957), Klassen and Mokrousov (1963), and GIembotsky et al. (1963). It emphasizes mainly the surface chemical aspects of the process, leaving other relevant topics such as hydrodynamics, mechanical and electrical technology, cir cuit design and engineering, operations research, instrumentation tech nology, modeling, etc., to appropriate specialized treatments.

Handbook of Flotation Reagents: Chemistry, Theory and Practice: Flotation of Gold, PGM and Oxide Minerals, Volume 2 focuses on the theory, practice, and chemistry of flotation of gold, platinum group minerals (PGMs), and the major oxide minerals, along with rare earths. It examines separation methods whose effectiveness is limited when using conventional treatment processes and considers commercial plant practices for most oxide minerals, such as pyrochlore-containing ores, copper cobalt ores, zinc ores, tin ores, and tantalum/niobium ores. It discusses the geology and mineralogy of gold, PGMs, and oxide minerals, as well as reagent and flotation practices in beneficiation. The book also looks at the factors affecting the floatability of gold minerals and describes PGM-dominated deposits such as Morensky-type deposits, hydrothermal deposits, and placer deposits. In addition, case studies of flotation and beneficiation in countries such as Canada, Africa, Russia, Chile, and Saudi Arabia are presented. This book will be useful to researchers, university students, and professors, as well as mineral processors faced with the problem of beneficiation of difficult-to-treat ores. Looks at the theoretical aspects of flotation reagents Examines the practical aspects of using chemical reagents in operating plants Provides guidelines for researchers and engineers involved in process design and development

"Electrochemistry of Flotation of Sulphide Minerals" systematically covers various electrochemical measurements, especially electrochemical corrosive methods, electrochemical equilibrium calculations, surface analysis, semiconductor energy band theory as well as molecular orbital theory. Behaviour and mechanism of collectorless and collector-induced flotation of sulphide minerals in various flotation systems are also discussed. The example of electrochemical flotation separation of sulphide ores shows an industrial application. Prof. Yuehua Hu is a professor at the School of Minerals Processing & Bioengineering of Central South University and Vice Chairman of the Mineral Processing Committee of the China Nonferrous Metals Society. Dr. Wei Sun is an associate professor at the School of Minerals Processing & Bioengineering of Central South University. Prof. Dianzuo Wang is both a member of Chinese Academy of Sciences and Chinese Academy of Engineering, and a foreign associate of the National Academy of Engineering (USA).

K.J.Ives Professor of Public Health Engineering University College London Industrial application of the use of bubbles to float fine particles in water began before the beginning of this century, in the field of mineral processing. Such bubble flotation was applied very little outside mineral processing, until about 1960 when the dissolved air process, which has already had some success in the pulp and paper industry, was applied to water and wastewater treatment. The subsequent two decades saw not only a growth development for water and wastewater treatment, but also a growing cognisance of the similarities that existed with mineral processing flotation. Therefore the time seemed ripe in 1982 for a joint meeting between experts in these two major fields of flotation to put together the Scientific Basis of Flotation in the form of a NATO Advanced Study Institute. Attended by about 60 specialists, mainly post doctoral, from 17 countries, this Study Institute in residence for two weeks in Christ's College, Cambridge (UK) heard presentations from several international experts, principally the 8 co-authors of this book. The integration of the various scientific disciplines of physics, physical chemistry, colloid science, hydrodynamics and process engineering showed where the common basiS, and occasional important differences, of flotation could be applied to mineral processing, water and wastewater treatment, and indeed some other process industries (for example: pharmaceuticals, and food manufacture).

Keeping pace with explosive developments in the field, Colloidal Science of Flotation reviews and updates the fundamentals of the bubble-particle collection phenomenon using a self-consistent approach that helps readers understand the hydrodynamic aspects of bubble-particle collection. The authors examine bubble rise velocity, water velocity around air bubbles, the thinning of intervening liquid films, the stability of particle-bubble aggregates, and macroscopic processes in froth. They also survey the applicability of emerging technologies in industrial flotation deinking, wastewater treatment, flotation of plastics, and improvements in minerals and coal flotation.

The characteristic feature of the flotation process is the interaction of gas bubbles with solid particles in a dispersion medium. This monograph reviews the state of the art from the point of view of colloid science, i.e. the heteroparticle interaction. A number of process engineering aspects and physically-based approaches to modelling the flotation process are also taken into account. Special emphasis is on: hydrodynamic interaction of bubble-particle flow; properties, stability and significance of thin liquid films formed as bubbles and particles collide; kinetics of three-phase contact mobility; balance of forces between adhering particles and gas bubbles under static and nonstatic conditions (stability of bubble-particle aggregates).Trends for new applications are discussed and concise descriptions given of new laboratory methods of use to workers in colloids and interfaces. All essential topics are described and derived mathematically in order to enable the reader to calculate the numerical values of interest to him.

Fluid Inclusion Effect in the Flotation of Sulfide Minerals gives a detailed introduction to how fluid inclusions affect the flotation of sulfide minerals. The book introduces the various fluids found in geology, detailing the properties of fluid inclusions and how to identify and analyze their composition. It gives the common chemical compositions of fluid inclusions, investigates the release of fluid inclusions in sulfide materials and some gangues, and presents the concentrations and solution chemistry of the released ions.
