Download or read book Surface Chemistry of Froth Flotation written by Jan Leja and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 772 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Surface Chemistry of Froth Flotation written by S. Ramachandra Rao and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 793 pages. Available in PDF, EPUB and Kindle. Book excerpt: th The technology of froth flotation, invented in the early 20 century was first used for the concentration of sulfide minerals. Since then it has been applied for the processing of many nonsulfide ores as weIl, including oxides, carbonates, silicates, soluble minerals like halite and sylvite and energy minerals like coal and bitumen. In recent years it has been used for several nonrnineral applications, such as waste water treatment, deinking of paper for recycling and resource recovery from industrial wastes he technology continues to grow with new applications reported every year. Flotation is based on chemical phenomena occurring at the interfaces, solid/water and air/water. Surface Chemistry principles have played a significant role in the development of flotation technology. Knowledge of aqueous solution chemistry and electrochemistry has added to our understanding of the reactions in flotation systems. Professor Jan Leja's book has weIl served researchers and students as they tried to understand the chemistry of flotation, and it is a significant contribution to the advancement of knowledge. However, since the book was first published, new research techniques and ever growing information have made an update necessary. The revised edition compiled by Dr. S. R. Rao has brought together fundamental aspects of the chemistry of flotation and how they apply to practical systems. It should serve all who are working in the area of flotation and interested in exploring new applications of flotation technology.

Available in PDF, EPUB and Kindle. Book excerpt: Due to the increasingly complex mineralogy, and lower grade of many current ore reserves, technology has, over the past decade, had to evolve rapidly to treat these materials economically in an industry which has undergone severe periods of recession. However, most of the technical innovations, such as the increasing use of solvent-extraction, ion-exchange etc., have been in the field of chemical ore processing, and, apart from the use of computers and ever larger unit process machines, there have been few major evolutionary changes in the field of physical mineral processing, where conventional crushing and grinding methods, essentially unchanged in half a century, are followed by the 'old-faithfuls'- flotation, gravity, magnetic and electrostatic methods of separation. Many of these techniques have major limitations in the treatment of 'new' ores such as complex sulphides, and the main purpose of the NATO Advanced study Institute (ASI) "Mineral Processing at a Crossroads" was to review the future of mineral processing. One of the great failings of physical methods is their inability to treat ultra-fine particles, and much research effort is required in this area. Flotation is still the most widely used and researched method for separating minerals, and is the only method which can be used to produce separate concentrates from complex sulphide ores. However, its performance on these 'modern' ores is poor, and it is in this area particularly that chemical methods will increasingly be integrated into plant circuits.

This book was released on 2012-12-02 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallurgical Applications of Bacterial Leaching and Related Microbiological Phenomena is a collection of papers presented at the International Symposium on Metallurgical Applications of Bacterial Leaching and Related Microbiological Phenomena, held in New Mexico Institute of Mining & Technology, Socorro, New Mexico on August 3-5, 1977. This book is organized into three sections encompassing 26 chapters. Section I emphasizes the role of microorganisms in the kinetics of leaching and similar metallurgical processes by stimulating a strong interaction between microbiologists and metallurgists. This section also discusses the basic study of microorganisms, in the strictly microbiological aspects of metal extraction and attendant conversion kinetics, and in the practical, engineering aspects of extraction. Section II deals with the microbiological leaching of waste materials, such as fly ash, slags, and jarosite-type leach residues. This section also describes a microbiological process for the recovery of sulfur in its elemental form from sulfate and sulfuric acid-containing aqueous wastes that are to be released in the environment. A microbiological leaching process for the removal of inorganic sulfur contained in coal is also described in this section. Considerable chapters in Section III are devoted to the specific applications of bacterial leaching, the optimization of the leaching conditions, and process optimization based upon economic considerations. This section also examines the advantages of large-scale testing compared with laboratory-testing. Workers in the fields of microbiology, biophysics, biochemistry, mineral processing and preparation, extractive and/or chemical metallurgy, mining engineering, and many related disciplines, including chemical and bioengineering, will find this book invaluable.

Download or read book Electronic Structure and Surfaces of Sulfide Minerals written by Jianhua Chen and published by Elsevier. This book was released on 2020-04-23 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electronic Structure and Surfaces of Sulfide Minerals: Density Functional Theory and Applications examines the mineral structure and electronic properties of minerals and their relationship to mineral floatability by density functional theory (DFT). This pragmatic guide explores the role of minerals in flotation by focusing on the mineral surface structure, electronic properties, and the adsorption of flotation agents through the study of the microscopic mechanism of reagents from the structure and properties of minerals. The flotation mechanism is explained from the point-of-view of solid physics, which is of great significance for both theoretical research and practical applications. The study of the structure and properties of the minerals can reveal the essential nature of mineral flotation, hence why minerals have floatability, the mechanism of response of different minerals to different chemicals, and the origin of the selectivity of flotation agents. - Discusses the relationship between mineral properties and floatability in terms of crystal structure, atomic coordination structure and electronic properties - Covers the influence of the surface structure of the mineral on surface charge distribution, reactivity and electron density, including a quantitative calculation method for the atomic reactivity of the mineral surface - Includes research on the microstructure and mechanism of reagent molecules adsorption on the surface of minerals, focusing on the interactions between water molecules, oxygen molecules and reagents
