Iron Ore Agglomeration Process

Iron ore agglomeration is a wet agglomeration process, and moist green balls are subsequently dried and heat hardened at high temperatures to make pellets the presence of binders affects the entire process from green ball formation to pellet hardening. Agglomeration Process In Pellet maydesign.


A binder for use in agglomerating finely divided iron ore materials, e.g., concentrates, is prepared from an iron-bearing material known on the Mesabi Range of Minnesota as paint rock. This is a red or orange, fairly soft and extremely sticky mineral consisting essentially of hematite, kaolinite and quartz, and having a high-ignition loss and high-moisture content.
