Download or read book Production of Manganese Ferroalloys written by Sverre E. Olsen and published by Tapir Academic Press. This book was released on 2007 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1973 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infrared absorption spectroscopy has been demonstrated to be a valuable method for studying the mineralogy and genesis of economically important ferromanganese deposits. Results are presented which demonstrate the usefulness of deterring both bulk mineralogy from infrared spectra of representative samples and structural states of individual minerals from spectra of pure single grains as small as 150 [mu]m. Spectra on isolated singles grains were obtained using the same infrared microsampling techniques recently developed specifically for analysis of fine-grained lunar rocks and dusts. These studies show that it is now possible to correlate infrared data with that from other microanalytical techniques and that the method yields valuable supplemental information. Several recommendations for additional in-depth studies on ferromanganese deposits using infrared microanalysis are outlined.

Available in PDF, EPUB and Kindle. Book excerpt: This chapter examines the theory and technology applied for the production of manganese ferroalloys. The focus is on smelting of ferromanganese, silicomanganese, and manganese metal in electric furnaces with different process types. The properties of manganese as well as its major compounds, minerals, and ores are presented. Agglomeration methods used to prepare ores for smelting are described. Refining techniques for low-carbon manganese ferroalloys are discussed, and postprocessing operations are outlined, together with tapping and casting processes. Additionally, the energy balance of manganese alloys smelting is outlined, and some potential hazards of the smelting technology are discussed, together with their preventive actions.
