Ferromanganese a ferroalloy with high manganese content, as much as 80% Mn by weight.
It is made by heating a mixture of the oxides MnO2 and Fe2O3, with carbon (usually as coal and coke) in either a blast furnace or an electric arc furnace-type system , called a submerged arc furnace. The oxides undergo carbothermal reduction in the furnaces, producing the ferromanganese.
Usage : Ferromanganese is used as a deoxidizer for steel.
