· Direct reduced iron (DRI) is also known as sponge iron (Hasambeigi et al. 2014 ). This high porous material has a metallization degree in the range 85–95% with a carbon content in the range 0.5–4% depending on the processing route. During the process, the iron oxides are reduced at the solid state.

· Usually, Iron Ore is manufactured and converted into Pellets. These are oval lumps of iron ore that are hardened using fuel. This process of converting iron ore into pellets is known as Pelletization. Iron Ore Pellets are then used in the production of steel.
