Book Description
A process for the recovery of copper and cobalt from the Kakanda tailings dump was developed and evaluated during an integrated pilot plant campaign at Mintek. The process involved a number of unit operations including leaching, copper solvent extraction, copper electrowinning, iron removal, manganese solvent extraction, cobalt solvent extraction, ion exchange for impurity removal, and cobalt electrowinning. This paper describes the laboratory test programme required to enable the design of an ion exchange circuit for the removal of traces of copper and zinc from the cobalt advance electrolyte, as well as the pilot plant campaign to evaluate the final design.^L^LA resin was chosen for the removal of copper, and occasionally copper and zinc, from the cobalt advance electrolyte. During the pilot plant campaign a lead-lag fixed-bed system was evaluated at a superficial linear velocity of 0.5 cm/s (to be employed on the full-scale plant). The concentration of copper in the ion exchange feed varied between 60 and 100 mg/l and that of zinc between less than 2 and 10 mg/l. Effluent concentrations for both metals of less than 2 mg/l, specified for electrowinning, were consistently delivered for both metals. ^L^LThe full- scale design was based on an ion-exchange feed flowrate of 200 m3/h, and the final dimensions of the two columns were: inside diameter 3.7 m, and height 7.5 m. Variations of copper and zinc concentrations in the ion exchange feed solution were accommodated by changes in the operating strategy of the plant during piloting.

Book Description
The sustainable use of natural resources is an important global challenge, and improved metal sustainability is a crucial goal for the 21st century in order to conserve the supply of critical metals and mitigate the environmental and health issues resulting from unrecovered metals. Metal Sustainability: Global Challenges, Consequences and Prospects discusses important topics and challenges associated with sustainability in metal life cycles, from mining ore to beneficiation processes, to product manufacture, to recovery from end-of-life materials, to environmental and health concerns resulting from generated waste. The broad perspective presented highlights the global interdependence of the many stages of metal life cycles. Economic issues are emphasized and relevant environmental, health, political, industrial and societal issues are discussed. The importance of applying green chemistry principles to metal sustainability is emphasized. Topics covered include: • Recycling and sustainable utilization of precious and specialty metals • Formal and informal recycling from electronic and other high-tech wastes • Global management of electronic wastes • Metal reuse and recycling in developing countries • Effects of toxic and other metal releases on the environment and human health • Effect on bacteria of toxic metal release • Selective recovery of platinum group metals and rare earth metals • Metal sustainability from a manufacturing perspective • Economic perspectives on sustainability, mineral development, and metal life cycles • Closing the Loop – Minerals Industry Issues The aim of this book is to improve awareness of the increasingly important role metals play in our high-tech society, the need to conserve our metal supply throughout the metal life cycle, the importance of improved metal recycling, and the effects that unhindered metal loss can have on the environment and on human health.

Book Description
With both nickel and cobalt featuring heavily in modern industry, there is an ongoing and intense interest in ore supplies and processing, applications development, and recycling. This book presents a collection of authoritative papers covering the latest advances in all aspects of nickel and cobalt processing, including fundamentals, technology, operating practices, and related areas of Platinum-Group Metals (PGM) processing. Special emphasis is given to the treatment of sulphide and laterite ores, concentrates, and secondary materials for the production of nickel and cobalt.

Book Description
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
