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 %).
World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron.
