Pelletization is the process in which iron ore is concentrated before shipment, thus significantly reducing the cost of transportation, and providing an essential feedstock for blast furnaces.
Details
The pelletization process is an established and economical route for enhanced utilization of the beneficiated micro-fines. The pellet feed is produced by mixing iron ore fines (-150 µm) with additives and a binder to meet the pellet quality requirements. The feed is then formed into spherical-shaped green pellets of 9–16 mm in diameter.
