The iron ore production has significantly expanded in recent years owing to increasing steel demands in developing countries However the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking This chapter shows the status of the 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

Iron ore pellets are spheres of typically 6–16 mm (0 24–0 63 in) to be used as raw material for blast furnaces They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets Typically limestone dolomite and olivine is added and Bentonite is used as binder The process of pelletizing combines

15 1 Introduction Iron ore lump sinter and pellets comprise the main burden of modern blast furnaces However sinter and pellets are now the dominant blast furnace burden because the natural lump supply has declined dramatically due to depletion of the world's high-grade competent iron ore resources
