The current technological challenges mean that engineers are expected to apply the available extraction in the field of extractive metallurgy. Extraction of copper, one of the most used metals, has been practiced since ancient times around the world. Three crucial steps, namely sulphide roasting, leaching of ores and concentrates, and electro-extraction through solvent extraction, are described here with ample details, diagrams, examples and explanations to enlighten practitioners. these techniques are widespread where copper ores are mined. These modes of extraction are applied in operations for many non-ferrous metals from where the interest of this book which enters in the collection of Extractive Metallurgy. Roger RUMBU, Met.

Hydroxyoximes and Copper Hydrometallurgy provides a current examination of what is known regarding hydroxyoxime extractants, the chemistry and physicochemistry of extraction, and the potential of applying hydroxyoximes for extraction of copper and other metals in industrial processes. Topics addressed include the development of the hydrometallurgical process, methods of synthesis and structural characteristics, extraction properties, losses of active substances and problems associated with environmental pollution, the potential of metal extraction and separation with hydroxyoximes, methods of extraction and stripping that can improve metal separation and recovery, the applications of hydroxyoximes in various membrane processes, and industrial processes and equipment used for processing oxide ores and tailing. The book will benefit metallurgists, hydrometallurgists, analytical and physical chemists, and researchers in mining industries and solvent extraction.

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 is based on the undergraduate and MSc courses in hydrometallurgy which Professor A R Burkin gave from 1961 until he retired in 1988. It is divided into two sections. The first deals with the fundamental chemical and physical principles on which the technology is based. In the second, processes which are used for the production of individual metals are described, in terms of those principles where appropriate.

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
