  • Iron Ore Pelletizing Process An Overview IntechOpen

    2018-7-11 · 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 pelletizing process
