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...
