Extractive Metallurgy Of Copper

A completely revised and up-to-date edition containing comprehensive industrial data. The many significant changes which occurred during the 1980s and 1990s are chronicled. Modern high intensity smelting processes are presented in detail, specifically flash, Contop, Isasmelt, Noranda, Teniente and direct-to-blister smelting. Considerable attention is paid to the control of SO2 emissions and manufacture of H2SO4. Recent developments in electrorefining, particularly stainless steel cathode technology are examined. Leaching, solvent extraction and electrowinning are evaluated together with their impact upon optimizing mineral resource utilization. The volume targets the recycling of copper and copper alloy scrap as an increasingly important source of copper and copper alloys. Copper quality control is also discussed and the book incorporates an important section on extraction economics. Each chapter is followed by a summary of concepts previously described and offers suggested further reading and references.

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

Extractive Metallurgy of Copper details the process of extracting copper from its ore. The book also discusses the significance of each process, along with the concerns in each process, such as pollution, energy demand, and cost. The text first provides an overview of the metallurgical process of copper extraction, and then proceeds to presenting the step-by-step representation of the whole process of copper extraction. The coverage of the book includes mineral beneficiation, roasting, smelting, converting, refining, casting, and quality control. The text will be of great use to metallurgists, materials engineers, and other professionals involved in mining industry.

Extractive Metallurgy of Copper, Sixth Edition, expands on previous editions, including sections on orogenesis and copper mineralogy and new processes for efficiently recovering copper from ever-declining Cu-grade mineral deposits. The book evaluates processes for maintaining concentrate Cu grades from lower grade ores. Sections cover the recovery of critical byproducts (e.g., cesium), worker health and safety, automation as a safety tool, and the geopolitical forces that have moved copper metal production to Asia (especially China) and new smelting and refining processes. Indigenous Asian smelting processes are evaluated, along with energy and water requirements, environmental performance, copper electrorefining processes, and sulfur dioxide capture processes (e.g., WSA). The book puts special emphasis on the benefits of recycling copper scrap in terms of energy and water requirements. Comparisons of ore-to-product and scrap-to-product carbon emissions are also made to illustrate the concepts included. Describes copper mineralogy, mining and beneficiation techniques Compares a variety of mining, smelting and converting technologies Provides a complete description of hydrometallurgical and electrometallurgical processes, including process options and recent improvements Includes comprehensive descriptions of secondary copper processing, including scrap collection and upgrading, melting and refining technologies
