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.

The Complete Book on Ferroalloys (Ferro Manganese, Ferro Molybdenum, Ferro Niobium, Ferro Boron, Ferro Titanium, Ferro Tungsten, Ferro Silicon, Ferro Nickel, Ferro Chrome) An alloy is a mixture or solid solution composed of metals. Similarly, Ferroalloys are the mixture of Iron with high proportion of other elements like manganese, aluminium or silicon. Alloying improves the physical properties like density, reactivity, Youngs modulus, electrical and thermal conductivity etc. Ferroalloys thus show different properties as mixture of different metals in different proportion exhibit a wide range of properties. Also, Alloying is done to alter the mechanical properties of the base metal, to induce hardness, toughness, ductility etc. The main demand of ferroalloys, nowadays is continuously increasing as the major use of such products are in the field of civil construction; decorative items; automobile; steel industry; electronic appliances. The book provides a wide idea to readers about the usage of appropriate raw material and the treatment involved in the processing of raw material to final produce, safety, uses and properties of raw material involved in the processes. This book concisely presents the core principles and varied details involved in processing of ferroalloys. The work includes detailed coverage of the major products like ferroaluminium, ferrosilicon, ferronickel, ferromolybdenum, ferrotungsten, ferrovanadium, ferromanganese and lesser known minor ferroalloys. Progress in thermodynamics and physico-chemical factors in ferroalloy production has developed rapidly during the past twenty-five years or so. The book presents the principles and current knowledge of processes in the production of various ferroalloys. The production of a particular ferroalloy involves a number of processes to be followed in order to give the alloy desired physical and mechanical properties. The slight difference in the temperature or heating or composition can lead to entirely different alloy with different properties. This book is not only confined to the different processes followed in the production of ferroalloys but also describes the processes used and other information related to product, which are necessary for the manufacturers knowledge. Also, the book gives the reader appropriate knowledge regarding the selection the best of available raw materials.

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.

Plasma-arc technology provides an alternative method for the treatment of ferro-alloys, in which disadvantages can be obviated to some extent. The three basic processes that are applicable to the production and treatment of manganese ferro-alloys are: the smelting of the ore, the remelting of ferro-alloy fines or other physically unacceptable forms of the alloys, and the refining of the alloys to yield a product with a lower carbon or silicon content than that of the alloy produced initially. In the present study, plasma technology was applied to the production of manganese ferro-alloys, and its suitability was evaluated in the context of these three processes. Two furnaces were used in the tests: a 1400 kVA furnace manufactured by Tetronics Research and Development Limited (TRD) and a 100 kVA furnace at Mintek. Both furnaces employ direct current (dc), and operate with a single electrode as the cathode and the molten bath as the anode. The molten pool of process material forms an integral part of the electrical circuit, and the furnaces used in the experiments can therefore be classified as dc transferred-arc plasma furnaces. In the 1400 kVA furnace, a water-cooled tungsten cathode (plasma gun) was used; in the 100 kVA furnace, graphite or water-cooled tungsten was used as the cathode material. High-carbon ferromanganese fines were successfully remelted in the Mintek 100 kVA and the TRD 1.4 MVA furnaces. The TRD furnace was operated at a power level of 450 kW, and about 4.5 t of metal was tapped continuously over a period of 8 hours. The specific energy consumption was 795 kW.h per ton of metal produced, and the losses of manganese in the baghouse represented less than 1 per cent of the manganese in the feed. Silicomanganese was produced in the Mintek 100 kVA furnace by the simultaneous remelting of high-carbon ferromanganese and silicon fines. A sufficiently low level of carbon could be reached to meet the chemical requirements of a regular-grade silicomanganese, and the recoveries of manganese and silicon were 97 and 82 per cent respectively. In some instances, the carbon content of the product was even lower than its initial level in the silicon fines, indicating that the conditions for the removal of the carbon in the plasma system are very favourable. Experiments in the Mintek 100 kVA furnace demonstrated that, when high-carbon ferromanganese is refined by manganese ore at temperatures around 1600 degrees C, ferromanganese containing about 2 per cent carbon and 0.1 per cent silicon can be produced. Satisfactory results were obtained on synthetic ores with basicities of 1.4 and 2.4 at metal-to-ore ratios of 2:1. The overall losses of manganese were between 10 and 15 per cent. High-carbon ferromanganese was produced from manganese-ore fines in the Mintek 100 kVA and the TRD 1.4 MVA furnaces. The manganese oxide contents of the resulting slags were significantly lower than those reported for submerged-arc furnaces. The losses of manganese to the dust stream, however, were substantial and, at the least, about 10 per cent of the manganese in the feed was lost by evaporation and entrainment. The relatively small scale of operation and the use of finely sized feed materials probably enhanced the losses of manganese, which were substantially higher than in conventional submerged-arc furnaces. It would appear that, because of the open-bath configuration and the absence of a burden of charge material, the areas over which the feed materials and power are conveyed to the reaction zone should be optimized and controlled more carefully if the recoveries obtained by industry are to be attained. Further work is required so that losses to the dust can be reduced and the benefits that would result from the utilization of finely sized manganese ores and reducing agents can be realized. This is especially important to the possible future production of upgraded ore fines with high manganese-to-iron ratios from relatively low-grade ore deposits, and because fine reducing agents will be available from coal deposits where the beneficiation process necessitates reduction of the coal ore to fine particles.
