About this ebook
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

About the author
Frank K. Crundwell is Director of Crundwell Metallurgy Limited, London, UK, CM Solutions (Pty) Ltd and is a Visiting Professor at the University of the Witwatersrand, South Africa. He has worked in research institutes, industrial refineries, academia and consultancies. He founded CM Solutions back in 2002, a sustainable laboratory and consultancy to the metallurgical industry. It develops flowsheets for a large variety of metals, such as copper, cobalt, gold platinum-group metals, nickel, and zinc, with a current focus on high purity products. Frank has more than 40 years' experience in studying dissolution reactions, and more than 70 publications in the area. He has been awarded the Milton E. Wadsworth Award of the Society for Mining, Metallurgy and Exploration for "innovative, rigorous contributions that have enhanced fundamental understanding of the mechanisms of oxidative and non-oxidative leaching of minerals including sulfides, oxides and silicates. He was elected to the prestigious National Academy of Engineering (US) for this work. He has contributed to and solved several debates in the field: (i) how bacteria interact with minerals, (ii) mechanisms of quartz and silica dissolution (iii) how impurities impact dissolution. In addition, he has contributed to the electrochemical theory of dissolution, extending it to apply to dissolution of semiconductors. He previously co-authored the Elsevier book Extractive Metallurgy of Nickel, Cobalt and Platinum Group Metals (2011) with Michael Moats, Venkoba Ramachandran, Timothy Robinson, and W. G. Davenport.
