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
