The mill scale was used to prepare iron metal powder of 98% purity by reducing carbon monoxide gas (CO) at 1050°C for 3 hrs. Hydrogen reduction reduced carbon and oxygen contents to acceptable values (0.23% and 0.28%) [8]. Recently, the mill scale was converted to sponge iron through reduction by coke at different temperatures and times.
