Iron ore pellets and Pelletizing processes – IspatGuru

Advantages of Pellets. 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 same both in the blast furnace and for DR production. Pellets have good reducibility since they have high porosity (2530%).

Effect of Fluxing Agents on the Quality and Microstructure

Indian iron ore fines with high alumina content (~2.5% Al 2 O 3 ) resulted in poor quality pellets and a study was under taken to establish suitable pellet chemistry through proper fluxing agents. Limestone fluxed pellets were prepared at varying basicity (0 to 0.8) and pyroxenite fluxed pellets at varying MgO contents (0 to 3%) to study their effect on the metallurgical properties.
