Book Description
This book is dedicated to the processes of mineral transformation, recycling and reclamation of metals, for the purpose of turning metals and alloys into a liquid state ready for pouring. Even though "process metallurgy" is one of the oldest technologies implemented by man, technological innovation, with the development of processes that are both focused on product quality and economically and ecologically efficient, continues to be at the heart of these industries. This book explains the physico-chemical bases of transformations, vital to their understanding and control (optimization of operational conditions), and the foundations in terms of "process engineering" (heat and matter assessment, process coupling: chemical reactions and transport phenomena), vital to the optimal execution and analysis of transformation process operations. This book is addressed to students in the field of metallurgy and to engineers facing the problem of metal and alloy development (operation of an industrial unit or development of a new process).

Book Description
Extractive metallurgy is the art and science of extracting metals from their ores and refining them. The production of metals and alloys from these source materials is still one of the most important and fundamental industries in both developed and developing economies around the world. The outputs and products are essential resources for the metallic, mechanical, electromagnetic, electrical and electronics industries (silicon is treated as a metal for these purposes). This series is devoted to the extraction of metals from ores, concentrates (enriched ores), scraps, and other sources and their refining to the state of either liquid metal before casting or to solid metals. The extraction and refining operations that are required may be carried out by various metallurgical reaction processes. Extractive Metallurgy 1 deals with the fundamentals of thermodynamics and kinetics of the reaction processes. Extractive Metallurgy 2 focuses on pyrometallurgical, hydrometallurgical, halide and electro-metallurgical (conversion) processes. Extractive Metallurgy 3 deals with the industrial processing operations, technologies, and process routes, in other words the sequence of steps or operations used to convert the ore to metal. Processes and operations are studied using the methodology of “chemical reaction engineering”. As the fundamentals of the art and science of Extractive Metallurgy are infrequently taught as dedicated university or engineering schools courses, this series is intended both for students in the fields of Metallurgy and Mechanical Engineering who want to acquire this knowledge, and also for engineers put in charge of the operation of an industrial production unit or the development of a new process, who will need the basic knowledge of the corresponding technology.

Book Description
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.

Book Description
Computer technology in the past fifteen years has essentially rev olutionized engineering education. Complex systems involving coupled mass transport and flow have yielded to numerical analysis even for relatively complex geometries. The application of such technology together with advances in applied physical chemistry have justified a general updating of the field of heterogeneous kinetics in extractive metallurgy. This book is an attempt to cover significant areas of extrac tive metallurgy from the viewpoint of heterogeneous kinetics. Kinetic studies serve to elucidate fundamental mechanisms of reac tions and to provide data for engineering applications, including improved ability to scale processes up from bench to pilot plant. The general theme of this book is the latter-the scale-up. The practicing engineer is faced with problems of changes of order of magnitude in reactor size. We hope that the fundamentals of heterogeneous kinetics will provide increasing ability for such scale-up efforts. Although ther modynamics is important in defining potential reaction paths and the end products, kinetic limitations involving molecular reactions, mass trans port, or heat flow normally influence ultimate rates of production. For this reason, rate processes in the general field of extractive metallurgy have been emphasized in this book.

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

Book Description
Mechanical activation of solids is a part of mechanochemistry, the science with a sound theoretical foundation exhibiting a wide range of potential application. Mechanical activation itself is an innovative procedure where an improvement in technological processes can be attained via a combination of new surface area and defects formation in minerals. Mechanical activation is of exceptional importance in extractive metallurgy and mineral processing and this area forms the topic of this book and is the result of more than twenty years of research and graduate teaching in the field. In pyrometallurgy, the mechanical activation of minerals makes it possible to reduce their decomposition temperatures or causes such a degree of disordering that the thermal activation may be omitted entirely. The potential mitigation of environmental pollutants is becoming increasingly important in this context. The lowering of reaction temperatures, the increase of the rate and amount of solubility, preparation of water soluble compounds, the necessity for simpler and less expensive reactors and shorter reaction times are some of the advantages of mechanical activation in hydrometallurgy. The environmental aspects of these processes are particularly attractive. Several industrial processes are examined and their flowsheets are presented as succesful of activation. In these processes, the introduction of a mechanical activation step into the technological cycle significantly modifies the subsequent steps. The book is designed for researchers, teachers, operators and students in the areas of extractive metallurgy, mineral processing, mineralogy, solid state chemistry and materials science.It will encourage newcomers to the mechanochemistry to do useful research and discover novel applications in this field.
