A large range of different products are pelletized including chemicals, iron ore, animal compound feed, and more. Pelletizing of iron ore produces spheres of typically 8 to 18 mm diameter. The process combines agglomeration and thermal treatment to convert the raw ore into pellets with characteristics appropriate for use in a blast furnace.

Iron ore pellets – IspatGuru

The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %).
