The properties of sponge iron produced by Midrex technology depend on the physical and chemical characteristics of the iron ore pellets as raw material. Iron ore Pellet is in the size range of 8 to 16 mm which charged into a shaft furnace of midrex plant. By increasing the size of the pellets, the amount of iron oxide and after that, the cold compressive strength has been decreased. When the FeO increases, and then the fine of sponge iron increases which reduces its quality.
