Utilised in iron making without agglomeration [3]. As the demand of iron ore is increasing, it is necessary to recover the resources from the mines wastes or lean-grade iron ore through beneficiation. In that case the feed to sinter or pellet can be recovered. Million tons of useful minerals are discarded in terms of fines and slimes every year.

Feb 23, 2013 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 ). Normally pellets are reduced considerably faster than sinter as well as iron ore lumps.

Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent. If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help.
