1 Introduction Manganese is an essential alloying element in the steel making process [ 1 ]. Many of the properties of the steel are achieved by appropriate addition of manganese ferroalloys. Basic manganese ferroalloys, viz. Ferromanganese (FeMn) and silicomanganese (SiMn), represent about 42% of the total ferroalloy production in India [ 2 ].
