What makes a metal precious? It’s rare, and it’s useful. When a metal is both these things, like gold, it’s very precious—and expensive. This book takes readers underground where they’ll discover the processes and elements that shape precious metals. They’ll learn about the features of metals that make them desirable, such as luster, ductility, and reactivity, and how certain metals are utilized. While readers may know something about gold and silver, they’ll become acquainted with other important precious metals such as rhodium and palladium. Vivid photographs, helpful graphic organizers, and interesting sidebars make this crucial science topic engaging and accessible.

The use of copper, silver, gold and platinum in jewelry as a measure of wealth is well known. This book contains 19 chapters written by international authors on other uses and applications of noble and precious metals (copper, silver, gold, platinum, palladium, iridium, osmium, rhodium, ruthenium, and rhenium). The topics covered include surface-enhanced Raman scattering, quantum dots, synthesis and properties of nanostructures, and its applications in the diverse fields such as high-tech engineering, nanotechnology, catalysis, and biomedical applications. The basis for these applications is their high-free electron concentrations combined with high-temperature stability and corrosion resistance and methods developed for synthesizing nanostructures. Recent developments in all these areas with up-to-date references are emphasized.

This book re-evaluates epidemiological and occupational health studies, experimental studies in animals and in vitro experiments relating to the toxicity of 27 metal and metalloid elements for which evidence of carcinogenicity has been presented. Human carcinogenic risk is substantiated in relation to arsenic, beryllium, thorium, chromium, radioactive elements, probably lead, and some nickel and cobalt compounds, and respirable silica particles, but the carcinogenicity of iron, aluminium, titanium, tungsten, antimony, bismuth, mercury, precious metals, and certain related compounds in humans is unresolved. The toxicity and carcinogenicity of each element is specific but correlates poorly with its position in the Periodic Table. Carcinogenicity differs according to the valency of the ion and its ability to interact with and penetrate membranes in target cells and to bind, denature or induce mutations by genotoxic or epigenetic mechanisms. This important text comprehensively examines each of the elements providing detailed information on the carcinogenicity and toxicity and detailing the most up-to-date research in this area. The book is an essential tool for toxicologists, medicinal and biochemists, and environmental scientists working in both industry and academia.

This book is the product of 50+ years of hands-on physiochemical work with both ferrous and nonferrous metals and with the metallurgy of refining, extracting, and casting. Its purpose is to cover the various methods of recovery and refining of precious metals. Both primary sources (placer gold, black sand, and ores) and secondary sources (scrap jewelry, electronic scrap, old films, buffings, spent plating and stripping solutions, catalytic automobile converters, and old eyeglass frames) are covered. The information contained in this volume is very basic and is intended for hands-on application and use. It is for nonchemist and chemist alike. I will not discuss the mathematical formulas for the various chemical reactions that take place-I leave them to the reader who wants to increase his working knowledge and understanding of chemistry. There are many courses offered in chemistry and extractive metallurgy, as well as a number of books available for self-study. The purpose of this book is to teach you how to perform various extractive, refining, and testing operations on precious metals (in various forms and states), with a resulting end product. You will learn how to perform operations in assaying and extraction, qualitative analysis, quantitative analysis, testing, classifying, and concentration-some of a purely mechanical nature, some of a chemical nature.

A view of gold and other precious metal extractions from a new and wider angle, taking in both the earth and the metallurgical sciences. To name but a small number of the topics covered: - Occurrences of gold and silver minerals in their ores - Photomicrographs of refractory and amenable minerals/ores - The use of irregular gold and silver distributions for efficient planning of the extraction process - Microanalytical techniques - Descriptions of uranium and many base metals for comparison. Written with a broad audience in mind, from the manager of operations to the metallurgist, for the field geologist or other earth scientist, and for the professor and student alike.
