2. Introduction To Pelletisation Process Pellets are spherical balls formed by the agglomeration of natural or ground iron ore fines in the presence of moisture and binder These green balls of 5 – 20mm size are then dried, preheated and fired at 1250 – 13500 C Bonding is developed between the fine ore particles at such high temperatures Additives like Bentonite, …

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking.
