role of laterite in sponge iron making

Ferroalloys - IspatGuru

Manganese plays an important role in the manufacturing of steel as deoxidizing, desulphurizing, and alloying agent. It is a mild deoxidizer than silicon but enhances the effectiveness of the latter due to the formation of stable manganese silicates and aluminates. It is used as an alloying element in almost all types of steel.
