Applications of Iron Ore Pellets & Iron ore Pelletization Process
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. Pellets are usually preferred instead of raw Iron Ore because it allows for maximum ...
