Physical Chemistry of Metallurgical Processes


Book Description

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.




Fundamentals of Metallurgical Processes


Book Description

Fundamentals of Metallurgical Processes, Second Edition reviews developments in the design, control, and efficiency of metallurgical processes. Topics covered include thermodynamic functions and solutions as well as experimental and bibliographical methods, heterogeneous reactions, metal extraction, and iron and steelmaking. This book is comprised of eight chapters and begins with an overview of the fundamentals of thermodynamics (functions, relationships, and behavior of solutions), followed by a discussion on methods of obtaining thermodynamic data from tables and graphs and by experiment. The kinetics of heterogeneous reactions in metallurgy are examined next, with particular reference to heterogeneous catalysis and mass transfer between immiscible liquid phases. The following chapters focus on the extraction of metals from oxides, sulfides, and halides; the production of iron and steel; the structure and properties of slags; slag/metal reactions; and equilibria in iron and steel production. The final chapter consists entirely of solved problems. This monograph will be of interest to metallurgists and materials scientists.




Handbook of Vacuum Arc Science & Technology


Book Description

This is a comprehensive text describing the basic physics and technological applications of vacuum arcs. Part I describes basic physics of the vacuum arc, beginning with a brief tutorial review of plasma and electrical discharge physics, then describes the arc ignition process, cathode and anode spots which serve as the locus for plasma generation, and resultant interelectrode plasma. Part II describes the applications of the vacuum arc for depositing thin films and coatings, refining metals, switching high power, and as sources of intense electron, ion, plasma, and x-ray beams.




Process Modeling in Pyrometallurgical Engineering


Book Description

The Special Issue presents almost 40 papers on recent research in modeling of pyrometallurgical systems, including physical models, first-principles models, detailed CFD and DEM models as well as statistical models or models based on machine learning. The models cover the whole production chain from raw materials processing through the reduction and conversion unit processes to ladle treatment, casting, and rolling. The papers illustrate how models can be used for shedding light on complex and inaccessible processes characterized by high temperatures and hostile environment, in order to improve process performance, product quality, or yield and to reduce the requirements of virgin raw materials and to suppress harmful emissions.

Physical Chemistry of Metallurgical Processes, Second Edition


Book Description

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.




Alternate Methods of Ironmaking


Book Description

This book has been prepared primarily for use by Students studying Ferrous Metallurgy (i.e., Iron and Steelmaking) at UG and PG level of Metallurgical and Materials Engineering, Research workers engaged in obtaining fundamental information in this field, and for Process Metallurgists to understand the processes in general and Sponge Iron Producers in particular. •; It also helps the practicing engineers who wish to apply the theoretical knowledge to the process they are operating. •;The book may very well be introduced as a Textbook for Elective subject in Third/Fourth year of UG programme in Metallurgical & Materials Engineering. •;The book consists of nine chapters in two parts; five chapters in Part-I: Direct Reduction Processes and four chapters in Part-II: Smelting Reduction Processes. In Part-I, the Chapter 1 deals with a brief introduction of the sponge iron and classification of the direct reduction processes with their advantages and limitations. Chapter 2 deals with the raw materials involved in direct reduced ironmaking and their characteristics. In Chapter 3, the physico-chemical principles and thermodynamics of reduction are highlighted. The details of different direct reduction (DR) processes are discussed in Chapter 4. The characteristics and uses of DRI as well as its effect on Electric Arc Furnace performance is discussed in Chapter 5.
