Applications of Iron Ore Pellets
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 utilization of iron ore. This is important since iron ore reserves are depleting globally.
