  • Iron Ore Pelletizing Process An Overview IntechOpen

    Jul 10 2017 · 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

  • Use of Boron Compounds as Binders in Iron Ore Pelletization

    Abstract Low grade iron ores with impurity gangue minerals containing silica and alumina must be upgraded to an acceptable level of iron content. Concentrates due to their fine sizes are not suitable to be directly charged to the iron-making processes such as the blast furnace or the DR-plant. Hence an agglomeration technique should be applied to fine concentrate.
