Electronic Structure and Surfaces of Sulfide Minerals Summary:

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

Sulfide Mineralogy and Geochemistry Summary:

Volume 61 of Reviews in Mineralogy and Geochemistry presents an up-to-date review of sulfide mineralogy and geochemistry. The crystal structures, electrical and magnetic properties, spectroscopic studies, chemical bonding, thermochemistry, phase relations, solution chemistry, surface structure and chemistry, hydrothermal precipitation processes, sulfur isotope geochemistry and geobiology of metal sulfides are reviewed. Where it is appropriate for comparison, there is brief discussion of the selenide or telluride analogs of the metal sulfides. When discussing crystal structures and structural relationships, the sulfosalt minerals as well as the sulfides are considered in some detail.

Fluid Inclusion Effect in Flotation of Sulfide Minerals Summary:

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. Finally, the book considers the absorption mechanism and the interaction of some typical metal ions from fluid inclusions on the surface of sulfide minerals. Analyzes the properties of a surface when in contact with a fluid inclusion and how the fluid released affects mineral processing and extraction Determines the heavy metals released from fluid inclusions Offers a comprehensive picture on how fluid inclusions affect flotation from both macro and microscopic viewpoints Presents the absorption mechanism and interactions of some typical metal ions from fluid inclusions on the surface of sulfide minerals

Surface Chemistry of Froth Flotation Summary:

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.
