Book Description :

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

Book Description :

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.

Book Description :

Volume 42 of Reviews in Mineralogy and Geochemistry covers the Applications in the Geosciences via Molecular Modeling Theory. We hope the content of this review volume will help the interested reader to quickly develop an appreciation for the fundamental theories behind the molecular modeling tools and to become aware of the limits in applying these state-of-the-art methods to solve geosciences problems. The review chapters in this volume were the basis for a short course on molecular modeling theory jointly sponsored by the Geochemical Society (GS) and the Mineralogical Society of America (MSA) May 18-20, 2001 in Roanoke, Virginia which was held prior to the 2001 Goldschmidt Conference in nearby Hot Springs, Virginia.

Book Description :

A set of surface-sensitive analytical techniques, collectively called scanning probe microscopy (SPM), has been developed and applied to a wide variety of materials. With SPM one can image nearly any surface in vacuum, in air, or in solution, and often can actually observe surfaces during reaction. Scanning tunneling microscopy (STM) and scanning force microscopy (SFM) have been used successfully in geosciences, and this volume introduces the theory and operation of SPM to clay mineralogists, summarises previous work using STM and SFM in mineralogy, and outlines the advantages and limitations of SPM for future research applications.

Book Description :

Minerals existed long before any forms of life, playing a key role in the origin and evolution of life; an interaction with biological systems that we are only now beginning to understand. Exploring the traditional strand of mineralogy, which emphasises the important mineral families, the well-established analytical methods (optical microscopy and X-ray diffraction) and the dramatic developments made in techniques over recent decades, David Vaughan also introduces the modern strand of mineralogy, which explores the role minerals play in the plate tectonic cycle and how they interact with the living world. Demonstrating how minerals can be critical for human health and illness by providing essential nutrients and releasing poisons, Vaughan explores the multitude of ways in which minerals have aided our understanding of the world. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Book Description :

Developments in Economic Geology, 4: Semiconducting Ore Minerals provides a comprehensive discussion of the semiconductor physics of ore minerals, which is a specialized field that is interdisciplinary to materials science and earth science. The book is organized into four parts. Part I deals with basic principles such as the electronic structure of solids; electrical conduction in semiconductors; and various crystal properties which, like conductivity, depend primarily upon the electronic structure. It also discusses theoretical and experimental investigations pertinent to complex electrical inhomogeneity. Part 2 examines the properties of elements such as bismuth, copper, and graphite. Part 3 deals with sulfides including arsenopyrite, bornite, chalcocite, chalcopyrite, covellite, molybdenite, pyrrhotite, and sphalerite. Part 4 covers oxides, including cassiterite, cuprite, hematite, magnetite, pyrolusite, and rutile. This book may be a useful reference for those involved with research on ore minerals, including geophysicists, geochemists, or extractive metallurgists.
