Ferroalloys

Production of blast furnace ferroalloys (lowgrade ferrosilicon and ferromanganese) is very small and gradually declining, since they are more contaminated and more expensive than electroferroalloys. Lowcarbon (refined) ferroalloys are produced by the metallothermic method (metallothermy) in electric arc (refining) furnaces with power MVA.
