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.

Decibel magazine is regarded as the best extreme music magazine around. Precious Metal gathers pieces from Decibel's most popular feature, the monthly “Hall of Fame” which documents the making of landmark metal albums via candid, hilarious, and fascinating interviews with every participating band member. Decibel's editor-in-chief Albert Mudrian, has selected and expanded the best of these features, creating a definitive collection of stories behind the greatest extreme metal albums of all time.

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.

A detailed look at how to profit in the precious metals market Today, gold, silver, platinum, and palladium offer a new and different profit potential for those who understand the impact of new technologies, new economic forces, and new demographics. Updated to reflect changes in this market since the mid-1990s, The Precious Metals Trader focuses on new developments that could translate into serious profit-making trends-from electrically-generated automobiles that could substantially increase demand for platinum to the increased use of composites in dentistry, which could negatively impact the use of both silver and gold. The Precious Metals Trader also explains the supply/demand fundamentals of the four precious metals-gold, silver, platinum, and palladium-and provides projections about long-term trends and profit opportunities that will coincide with them. Filled with fresh insights from Philip Gotthelf-one of the top experts in this field-The Precious Metals Trader offers readers the guidance they need to trade profitably within this dynamic market. Philip Gotthelf (Closter, NJ) publishes the Commodex System-the oldest daily futures trading system published in the world-and the Commodity Futures Forecast Service. He is also President of Equidex Incorporated and Equidex Brokerage Group Inc.

Written by an experienced enamel craftsperson, the book features stunning colour photography of her own work as well as that of many other enamellists, and will appeal to both practitioners and collectors alike.

The resources race is on. Powering our digital lives and green technologies are some of the Earth’s most precious metals — but they are running out. And what will happen when they do? The green-tech revolution has been lauded as the silver bullet to a new world. One that is at last free of oil, pollution, shortages, and cross-border tensions. Drawing on six years of research across a dozen countries, this book cuts across conventional green thinking to probe the hidden, dark side of green technology. By breaking free of fossil fuels, we are in fact setting ourselves up for a new dependence — on rare metals such as cobalt, gold, and palladium. They are essential to electric vehicles, wind turbines, solar panels, our smartphones, computers, tablets, and other everyday connected objects. China has captured the lion’s share of the rare metals industry, but consumers know very little about how they are mined and traded, or their environmental, economic, and geopolitical costs. The Rare Metals War is a vital exposé of the ticking time-bomb that lies beneath our new technological order. It uncovers the reality of our lavish and ambitious environmental quest that involves risks as formidable as those it seeks to resolve.

Precious metals and semi-precious metals are used for an increasing number of medical applications due to the properties of these metals and their alloys. Precious Metals for Biomedical Applications reviews the properties of precious metals and their resulting applications in medicine. Part one outlines the fundamentals of precious metals for biomedical applications, discussing their useful properties, such as biocompatibility and corrosion resistance. Part two goes on to provide an overview of the applications of precious metals in biomedicine, including dental, therapeutic, tissue engineering, and bioimaging applications. It discusses the advantages of the structure and properties of precious metals for these applications. Precious Metals for Biomedical Applications is a key reference for material scientists and academics concerned with the properties and uses of these metals.
