Although the silicothermic reduction process is more energy intensive than the decarburization of high-carbon ferromanganese, it has the advantage that the final carbon content is limited only by the carbon content of initial silicomanganese. The silicothermic process can therefore be used to produce LC ferromanganese and industrial manganese ...
