The smelter operations sessions presented more than 50 papers dealing with all aspects of pyrometallurgy. Topics included many industrial developments, including smelter modernization, waste -- heat boiler technology, gas cooling and heat recovery, sulfuric acid plant systems and designs, gas handling, efforts to refine the Pierce -- Smith converter process, Teniente technology, continuous processing, distribution and removal of impurities, Ausmelt technology smelter design, drying facilities, and furnace cooling design. Also included is a reprinted paper from the American Institute of Mining and Metallurgical Engineers meeting of 1899.
This new edition has been extensively revised and updated since the 3rd edition published in 1994. It contains an even greater depth of industrial information, focussing on how copper metal is extracted from ore and scrap, and how this extraction could be made more efficient. 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 book demonstrates how recycling of copper and copper alloy scrap is an 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.
Volume I contains plenary lectures addressing key issues confronting copper producers, namely future markets for copper, aspects of copper market forecasting, the financial performance of the industry, copper extraction technologies, and future developments and environmental constraints. This proceedings volume also includes eleven papers related to movement of copper and the industry's outlook, divided into the two broad areas of economics and finances and markets and trends. Six papers on new developments in the fabrication of copper-based alloys and materials and nine papers on a wide range of topics related to copper applications close out the volume.
Volume III contains 33 electrorefining and 15 electrowinning papers. The electrorefining papers provide a valuable record of the status of the industry and summarize research and development work in progress. The electrowinning section outlines the state of the industry and many supporting research activities. Topics include reduction of energy costs, stainless steel plating technology, and techniques to monitor and control impurities in the electrolyte. Lastly, several papers deal with modeling the electrorefining process to obtain better process control and enhance plant automation.
This updated, second edition retains its classroom-tested treatment of physical chemistry of metallurgical topics, such as roasting of sulfide minerals, matte smelting, converting, structure, properties and theories of slag, reduction of oxides and reduction smelting, interfacial phenomena, steelmaking, secondary steelmaking, role of halides in extraction of metals, refining, hydrometallurgy and electrometallurgy, and adds new data in worked-out examples as well as up-to-date references to the literature. The book further explains the physical chemistry of various metallurgical topics, steps involved in extraction of metals, such as roasting, matte smelting/converting, reduction smelting, steelmaking reactions, deoxidation, stainless steelmaking, vacuum degassing, refining, leaching, chemical precipitation, ion exchange, solvent extraction, cementation, gaseous reduction and electrowinning. Each topic is illustrated with appropriate examples of applications of the technique in extraction of some common, reactive, rare, or refractory metal together with worked out problems explaining the principle of the operation. The problems require imagination and critical analyses and also encourage readers for creative application of thermodynamic data in metal extraction. Updates and condenses text throughout the book by sequential arrangement of paragraphs in different chapters; Maximizes readers’ understanding of the physicochemical principles involved in extraction/production of common and rare/reactive metals by pyro- as well as hydrometallurgical routes; Reinforces concepts presented with worked examples in each chapter explaining the process steps; Explains the physical chemistry of various metallurgical steps, such as roasting, matte smelting/converting, and reduction smelting, steelmaking, aqueous processing etc. in extraction of metals; Collects and uniformly presents scattered information on physicochemical principles of metal production from various books and journals.
Volume VI groups its papers into three sections covering technology development, process modeling, and fundamentals. There is a focus on transport phenomena in both flash and bath smelting processes, mathematical modeling in support of process and equipment design and process control, and furnace refractories and cooling techniques leading to longer furnace campaign life. Some of the fundamental papers demonstrate that process chemistry is still an area of active research in universities.
This book covers various metallurgical topics, viz. roasting of sulfide minerals, matte smelting, slag, reduction of oxides and reduction smelting, interfacial phenomena, steelmaking, secondary steelmaking, role of halides in extraction of metals, refining, hydrometallurgy and electrometallurgy. Each chapter is illustrated with appropriate examples of applications of the technique in extraction of some common, reactive, rare or refractory metal together with worked out problems explaining the principle of the operation.
This title chronicles developments made in flash furnaces and the process of flash smelting. It is divided into a descriptive section and a mathematical section and this second updated edition includes the contributions of two authors and an updated mathematical approach.
