Although manganese oxides are used in iron and steel production due to their desulfurization and deoxidation capabilities, manganese grades in iron ores fed to furnaces should be < 1.5% Mn for direct charge ore and < 5% Mn for sintered ore . This is because Mn has a negative effect on iron ore reduction.
