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

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

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

This book examines the electronic structure of earth-abundant and environmentally friendly materials for use as absorber layers within photovoltaic cells. The corroboration between high-quality photoemission measurements and density of states calculations yields valuable insights into why these materials have demonstrated poor device efficiencies in the vast literature cited. The book shows how the materials’ underlying electronic structures affect their properties, and how the band positions make them unsuitable for use with established solar cell technologies. After explaining these poor efficiencies,
