Extractive Metallurgy I (EBT213/4)

Hydrometallurgy is a field of chemical technology concerned with the production of metals from their ores and secondary sources. This text analyses these processes, surveying new and emerging issues in the field.

Extract all the metals information you need! A wealth of data on metals and their extraction is revealed in this comprehensive handbook. The aim of this book is to provide a clear description of how a particular metal is extracted industrially from different raw materials, and on what its important compounds are. The present work is a collection of 58 articles written by over 280 specialists. It supplies thousands of top-quality illustrations, diagrams and charts, and provides hand-picked references ensuring the most up-to-date coverage. A unique feature of this reference work is its structure. The system used here is according to an economic classification, which reflects mainly the uses, occurrence and economic value of metals. First, the ferrous metals, i.e., those used in the production of iron and steel, are outlined. Then, nonferrous metals are subdivided into primary, secondary, light, precious, refractory, scattered, radioactive, rare earth, ferroalloy metals, and, finally, the alkali and the alkaline earth metals are described. The handbook is an essential aid for the practising metallurgist. Mining engineers, mineralogists, chemical engineers, chemists and geologists will find it a comprehensive desk reference. It is of interest to engineers and scientists in industry seeking an exhaustive sourcebook, and it should be present in every library.

Chemical metallurgy is a well founded and fascinating branch of the wide field of metallurgy. This book provides detailed information on both the first steps of separation of desirable minerals and the subsequent mineral processing operations. The complex chemical processes of extracting various elements through hydrometallurgical, pyrometallurgical or electrometallurgical operations are explained. In the choice of material for this work, the author made good use of the synergy of scientific principles and industrial practices, offering the much needed and hitherto unavailable combination of detailed treatises on both compiled in one book.

Rather than simply describing the processes and reactions involved in metal extraction, this book concentrates on fundamental principles to give readers an understanding of the possibilities for future developments in this field. It includes a review of the basics of thermodynamics, kinetics and engineering principles that have special importance for extractive metallurgy, to ensure that readers have the background necessary for maximum achievement. The various metallurgical unit processes (such as roasting, reduction, smelting and electrolysis) are illustrated by existing techniques for the extraction of the most common metals. Each chapter includes a bibliography of recommended reading, to aid in further study. The appendices include tables and graphs of thermodynamic qualities for most substances of metallurgical importance; these are ideal for calculating heat (enthalpy) balances and chemical equilibrium constants. SI Units are used consistently throughout the text.

This book describes and explains the methods by which three related ores and recyclablesare 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 metalsare 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 thisnecessitates amulti-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 plantsDiscusses Nickel, Cobalt and Platinum Group Metals for the first time in one bookReviews extractionof multiple metals from the same tropical or arctic oreIndustrial, international and multidisciplinary focus on current standards of production supports best practice use of industrial resources

The Extraction and Refining of Metals provides a novel approach to the science and technology of both ferrous and non-ferrous metal production. Rather than the traditional treatment in which one metal at a time is considered, this new approach, which examines several metals at a time, reveals more clearly the versatility and limitations of each of the main types of process. The restrictions imposed on the selection of the process routes by thermodynamic and kinetic factors and by economic and environmental constraints are examined in detail. The conservation of energy and materials is emphasized and illustrated by the description of new and improved extraction methods.The types of mathematical models that are being developed for computer control of production operations are indicated, and worked examples demonstrate relevant thermodynamic and mass balance calculations.

This multi-author new edition revises and updates the classic reference by William G. Davenport et al (winner of, among other awards, the 2003 AIME Mineral Industry Educator of the Year Award "for inspiring students in the pursuit of clarity"), providing fully updated coverage of the copper production process, encompassing topics as diverse as environmental technology for wind and solar energy transmission, treatment of waste by-products, and recycling of electronic scrap for potential alternative technology implementation. The authors examine industrially grounded treatments of process fundamentals and the beneficiation of raw materials, smelting and converting, hydrometallurgical processes, and refining technology for a mine-to-market perspective - from primary and secondary raw materials extraction to shipping of rod or billet to customers. The modern coverage of the work includes bath smelting processes such as Ausmelt and Isasmelt, which have become state-of-the-art in sulfide concentrate smelting and converting. Drawing on extensive international industrial consultancies within working plants, this work describes in depth the complete copper production process, starting from both primary and secondary raw materials and ending with rod or billet being shipped to customers. The work focuses particularly on currently-used industrial processes used to turn raw materials into refined copper metal rather than ideas working only on paper . New areas of coverage include the environmentally appropriate uses of copper cables in power transmission for wind and solar energy sources; the recycling of electronic scrap as an important new feedstock to the copper industry, and state-of-the-art Ausmelt and Isasmelt bath smelting processes for sulfide concentrate smelting and converting.
