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.

During the last three decades, there have been dramatic changes in the steel industry in terms of the quality of products, processing technology, energy efficiency, labor productivity and environmental protection. The once prominent role of the metals industry in national economies is declining in industrialized countries to the point where fewer research engineers are employed in the industry. The scope of this book is limited to selected topics within the field of Physical Chemistry of Iron and Steelmaking"that are relevant to reduction, refining and solidification steps in the steel industry. The authors, leaders in the field, have gathered the complex information regarding metallurgy in this collection to enable the next generation to take this branch of science, and the metals industry, to new heights. Graduate students and research engineers will find this book particularly useful, while practicing engineers, innovators and managers in technology developmentwill read and consult this book for inspiration and reference.

This book introduces beryllium; its history, its chemical, mechanical, and physical properties including nuclear properties. The 29 chapters include the mineralogy of beryllium and the preferred global sources of ore bodies. The identification and specifics of the industrial metallurgical processes used to form oxide from the ore and then metal from the oxide are thoroughly described. The special features of beryllium chemistry are introduced, including analytical chemical practices. Beryllium compounds of industrial interest are identified and discussed. Alloying, casting, powder processing, forming, metal removal, joining and other manufacturing processes are covered. The effect of composition and process on the mechanical and physical properties of beryllium alloys assists the reader in material selection. The physical metallurgy chapter brings conformity between chemical and physical metallurgical processing of beryllium, metal, alloys, and compounds. The environmental degradation of beryllium and its alloys both in aqueous and high temperature condition are presented. The health and environmental issues are thoroughly presented the current requirements and established practices for handling beryllium in the workplace are available. A thorough list of references will assist the user of this book.

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.

Primarily intended for the undergraduate students of metallurgical and materials engineering, this textbook will help the students to grasp the subject matter of extractive metallurgy in a simple and easy-to-understand manner. It presents a comprehensive view of extractive metallurgy, especially principles and fundamental aspects, in a concise form. The book explains various concepts step by step by narrating their importance. Even without much of background in specialized subjects, the students will be able to understand the topics without any difficulty. It covers a brief summary of the metallurgical processes including physical chemistry, thermodynamics, kinetics, and heat/mass balance. Many of the scientific and engineering aspects of unit processes have been discussed. Applications of metallurgical thermodynamics and kinetics to the process metallurgy are explained as well. All basic concepts and definitions related to metal extraction are also covered.

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.
