High carbon ferro manganese is produced entirely through submerged arc furnace route in India. This route has the greatest disadvantage of high electrical energy consumption. The manufacturers of ferro alloys are facing difficulties to stay competitive due to the increasing tariff of electric power. Ferro manganese can be manufactured in blast furnaces much more economically compared to submerged arc furnaces with cogeneration
of electric power using the BF off-gas. Some modifications
will be required in the design of conventional blast furnaces for producing ferro manganese. Tana Kotf mini blast furnaces can be conveniently used for the manufacture of FeMn, since most of these modifications
have already been incorporated in the design of these furnaces
