This comprehensive treatment of the smelting industry of Colorado, originally published in 1979, is now back in print with a new preface by the author. Packed with fascinating statistics and mining data, Ores to Metals details the people, technologies, and business decisions that have shaped the smelting industry in the Rockies. Although mining holds more of the glamour for those in and interested in the minerals industry, smelters have continuously played a critical role in the industry’s evolution since their introduction in Colorado in the 1860s. At that time, miners desperately needed new technology to recover gold and silver from ores resistant to milling. Beginning as small independent enterprises, progressing to larger integrated firms working in urban centers, and finally following a trend toward mergers, the entire industry was absorbed into one large holding company—the American Smelting and Refining Company. Over time, fortunes were won and lost, business success was converted to political success, and advances were made in science and metallurgy. Drawing on archival material, Fell expertly presents the triumphs and troubles of the entrepreneurs who built one of the great industries of the West.

Extensively revised and updated, this edition provides the broad base of knowledge required by all working in the gold extraction and gold processing industries. It bridges the gap between research and industry by emphasizing practical applications of chemical principles and techniques.

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.
