Direct Reduced Iron By-Product Fines (DRI D): A Guide …

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.
