iron ore burden is such that the ascending column of g ases interfaces with the maximum surface area of the iron ore - the higher the content of iron ore fines in the feedstock, the lower the permeability of the burden. The iron ore feedstock (pellets and lump ore) is therefore screened to remove fines before being charged to the furnace.

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 %).
