The primary use of ferromanganese is as a type of processed manganese source to add to different types of steel, such as stainless steel. Global production of lowcarbon ferromanganese ( alloys with less than 2% carbon content) reached megatons in 2010. [2] Production Sources of manganese ore generally also contain iron oxides.
