Iron ore pelletization technology is needed due to the increasing amount of iron ore fines produced during mining. Pellets have excellent properties for transportation and are needed to utilize low grade iron ores. The pelletization process involves forming green balls from iron ore fines and water, then drying, preheating, and heating the balls to form hard …

The majority of iron ores must be ground to a fine particle size to allow the iron oxides they contain to be concentrated, and the concentrate must then be agglomerated back into large enough particles that they can be processed in blast furnaces. The most common agglomeration technique is pelletization, which requires the use of binders to hold the …

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 …

ABSTRACT. The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the inter-particle bonding within the pellet.

ABSTRACT This part reviews the goals of introducing organic binders into iron ore pelletization. Organic binders present a relatively small number of unique binding options but provide an extraordinary amount of flexibility in how to apply them. The key factors that lead into an effective organic binder are good dispersion into the iron ore, …

Introduction Iron ore pellets are one type of iron-rich, intermediate product used during primary iron and steel making. During pellet production, fine-grained iron containing minerals are liberated from lowgrade ores, concentrated, and agglomerated into round balls that are thermally hardened to form "pellets". Pellets are then transported to Blast …
