Metals From Ores

This book describes and explains the methods by which three related ores and recyclables are made into high purity metals and chemicals, for materials processing. It focuses on present day processes and future developments rather than historical processes. Nickel, cobalt and platinum group metals are key elements for materials processing. They occur together in one book because they (i) map together on the periodic table (ii) occur together in many ores and (iii) are natural partners for further materials processing and materials manufacturing. They all are, for example, important catalysts – with platinum group metals being especially important for reducing car and truck emissions. Stainless steels and CoNiFe airplane engine super alloys are examples of practical usage. The product emphasises a sequential, building-block approach to the subject gained through the author’s previous writings (particularly Extractive Metallurgy of Copper in four editions) and extensive experience. Due to the multiple metals involved and because each metal originates in several types of ore – e.g. tropical ores and arctic ores this necessitates a multi-contributor work drawing from multiple networks and both engineering and science. Synthesizes detailed review of the fundamental chemistry and physics of extractive metallurgy with practical lessons from industrial consultancies at the leading international plants Discusses Nickel, Cobalt and Platinum Group Metals for the first time in one book Reviews extraction of multiple metals from the same tropical or arctic ore Industrial, international and multidisciplinary focus on current standards of production supports best practice use of industrial resources

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.

Rare Metal Extraction by Chemical Engineering Techniques describes the use of chemical engineering techniques in the extraction and purification of rare metals such as uranium, thorium, and zirconium as well as hafnium, titanium, beryllium, and vanadium. The various chemical extraction stages from ore to metal are discussed. Comprised of nine chapters, this book begins with an examination of ore breakdown processes including dilute acid leaching and the breakdown of concentrated acids, alkalis, and fluorides as well as chlorination. The reader is then introduced to ion-exchange purification; solvent extraction; and dryway conversion processes. Subsequent chapters focus on metal production by high-temperature reduction techniques; molten salt electrolytic processes; and iodide decomposition processes. The final chapter includes a selection of complete flowsheets for the extraction and purification rare metals from ores. This monograph will be of value to metallurgists, chemical engineers, chemists, and others who are interested in the extraction of rare metals.

Excerpt from Elements of Metallurgy: A Practical Treatise on the Art of Extracting Metals From Their Ores A great difficulty experienced in collecting statistics relative to the metal-production of the world arises from the fact that ores raised in one country are frequently subjected to metallurgical treatment in another, and the produce is, in the majority of instances, returned by both. Allowance for such double returns has, when practicable, been made, but the complete elimination of error arising from this cause would be exceedingly difficult. Sometimes no precise figures have been available, and in such cases estimates founded on the best procurable data have been substituted. Both the wet and dry methods of assaying are given with considerable detail, and when, as in the case of ironstones, the value of an ore is materially affected by the nature and quantity of the impurities present, the processes employed for their detection and estimation are fully described.
