Book Description
The process by which ore is converted to a ferroalloy contains a number of steps. These include mining of the ore; preparing the ore by processes such as crushing, screening, washing, grinding, or milling; and sometimes applying beneficiation processes such as flotation, followed by smelting and refining. This chapter describes the equipment used for the smelting of ferroalloys. The first section covers furnace technology and operation by discussing AC and DC furnaces, their electrical operation, electrodes, and related plant such as raw material handling systems, exhaust gas handling, and furnace crucibles, which includes the linings, and cooling of the furnace and the roof. The second section discusses the more important processing steps, which may be applied to the raw materials at the smelter prior to their smelting in the furnace. These include agglomeration by briquetting or the production of sintered pellets, sintering of ore, prereduction, and preheating. The third section describes the treatment of the product and slag after it leaves the furnace, whereas the final section provides a short description of other furnaces for ferroalloys production.

Book Description
This book outlines the physical and chemical foundations of high-temperature processes for producing silicon, manganese and chromium ferroalloys, alloys of molybdenum, vanadium, titanium, alkaline earth and rare earth metals, niobium, zirconium, aluminum, boron, nickel, cobalt, phosphorus, selenium and tellurium, iron-carbon alloys by carbon, silicone and aluminothermic methods. The chapters introduce the industrial production technologies of these groups of ferroalloys, the characteristics of charge materials, and the technological parameters of the melting processes. A description of ferroalloy furnaces is given in detail. Topics such as waste recycling, fines agglomeration technologies, and environmental issues are considered.

Book Description
The word ferroalloy refers to an alloy of iron containing a significant proportion of one or more other elements like silicon, manganese, chromium, aluminum, or titanium. The main applications of ferroalloys occur in the steelmaking process. They are added to steel to improve properties like strength, ductility, and fatigue or corrosion resistance. Additionally, ferroalloys can have several other tasks, such as in refining, deoxidation, modification, and control of nonmetallic inclusions and precipitates. The production and role of ferroalloys are briefly introduced, both from a historical perspective and in light of current and future prospects. Examples of production figures, producers, and markets are presented. Recent developments and main drivers in ferroalloys processing, including energy saving, environmental issues, primary and secondary raw materials resources, and development trends in technology, are briefly discussed.

Book Description
High carbon ferrochrome is one of the most common ferroalloys produced and is almost exclusively used in the production of stainless steel and high chromium steels. Production takes place primarily in countries with substantial chromite ore supply. Relatively cheap electricity and reductants also contribute to the viability of high carbon ferrochrome. The most common production technology utilized is submerged arc smelting in AC furnaces, although open arc smelting in DC furnaces is becoming increasingly common. A more advanced technology route that includes a prereduction step is only utilized at significant scale by one producer. Production processes have become more energy and metallurgically efficient by utilizing advanced processes such as prereduction, preheating, agglomeration of ore, and CO gas utilization. Recently installed plants display manageable risks in terms of environmental pollution and occupational health.

Book Description
This unique and practical book provides quick and easy access to data on the physical and chemical properties of all classes of materials. The second edition has been much expanded to include whole new families of materials while many of the existing families are broadened and refined with new material and up-to-date information. Particular emphasis is placed on the properties of common industrial materials in each class. Detailed appendices provide additional information, and careful indexing and a tabular format make the data quickly accessible. This book is an essential tool for any practitioner or academic working in materials or in engineering.

Book Description
Winner of the International Solid Waste Association's 2014 Publication Award, Handbook of Recycling is an authoritative review of the current state-of-the-art of recycling, reuse and reclamation processes commonly implemented today and how they interact with one another. The book addresses several material flows, including iron, steel, aluminum and other metals, pulp and paper, plastics, glass, construction materials, industrial by-products, and more. It also details various recycling technologies as well as recovery and collection techniques. To completely round out the picture of recycling, the book considers policy and economic implications, including the impact of recycling on energy use, sustainable development, and the environment. With contemporary recycling literature scattered across disparate, unconnected articles, this book is a crucial aid to students and researchers in a range of disciplines, from materials and environmental science to public policy studies. - Portrays recent and emerging technologies in metal recycling, by-product utilization and management of post-consumer waste - Uses life cycle analysis to show how to reclaim valuable resources from mineral and metallurgical wastes - Uses examples from current professional and industrial practice, with policy and economic implications

Book Description
Progress in our knowledge of thermodynamics and physico-chemical factors in manganese ferroalloy production has developed rapidly during the past twenty-five years or so. The authors' intention has been to use this basic knowledge in discussions of industrial manganese ferroalloy production. The book presents the principles and current knowledge of processes in the production of high carbon ferromanganese, silicomanganese and low carbon manganese alloys. The book is intended for professionals working in production, plant design or development. It will also be useful for researchers in industry, universities and research institutes. The book can be used as a textbook for courses in extractive and process metallurgy, and for company in-house courses. Thermodynamics of the slag and metal systems are extensively covered. Computational modelling based on assessed thermochemical databases has made it possible to calculate and present a large number of phase and equilibrium diagrams. These diagrams are useful for easy understanding and analysis of the complex heterogeneous equilibria in the manganese ferroalloy metallurgy. The manganese ferroalloys are mainly produced in electric submerged arc furnaces. Electrical relations are briefly discussed. Supply of raw materials, especially manganese ores and coke, is extremely important for the manganese industry. The book gives the reader appropriate knowledge regarding the selection the best of available raw materials. Environmental issues, including greenhouse gas emissions and climate changes, are of growing concern to ferroalloy producers. Carbon will always be needed as a reducing agent, and consequently emission of CO2 gas is inevitable. The book describes solutions to dealing with pollution problems and gives the latest guidelines for greenhouse gas inventories.
