Review of Organic Binders for Iron Ore Agglomeration

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 Furnace or Direct Reduction
