Electronic Structure and Surfaces of Sulfide Minerals

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

Volume 5A of this second edition of Rock-Forming Minerals focuses on oxides, hydroxides and sulphides. Since the publication of the first edition, in 1962, there has been an enormous increase in the literature devoted to these minerals. This new edition, greatly expanded and rewritten, covers aspects that include crystal structures, chemical compositions, electronic structures, phase relations, thermochemistry, mineral surface structure and reactivity, physical properties, distinguishing features and parageneses (including stable isotope data).

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

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,

Volume 23 of Reviews in Mineralogy and accompanying MSA short course covers chemical reactions that take place at mineral-water interfaces. We believe that this book describes most of the important concepts and contributions that have driven mineral-water interface geochemistry to its present state. We begin in Chapter 1 with examples of the global importance of mineral-water interface reactions and a brief review of the contents of the entire book. Thereafter, we have divided the book into four sections, including atomistic approaches (Chapters 2
