Review of Organic Binders for Iron Ore Agglomeration
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 low-grade ores concentrated and agglomerated into round balls that are thermally hardened to form "pellets".

Mineralogy of Iron Ores of Different Alumina Levels from
In the sintering process the iron ore corresponds to the mixture of hematite goethite and other gangue mineral typologies. However the goethite and gangue contents are relatively lower than the hematite but the goethite gangue to hematite ratio influences the reactivity during sintering. The minerals association in iron ores and their chemistries affect the formation and composition of
