What are the advantages of pelletizing iron ore?
There are several different sub-processes, or process segments, that make up the pelletising process. The iron ore passes through the following primary process steps on its journey from the mine to a finished product: Step 1: The iron ore is crushed, and the waste rock is removed. About 85 % of the particles should be less than 44 μm (in ...

Introduction to Iron ore Pellets and Pelletizing processes
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 %).
