A Look at the Process of Pelletizing Iron Ore for Steel ...

Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.

Introduction to Iron ore Pellets and Pelletizing

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 ...
