An assessment of the production of fine material in iron ...

Iron ore sinter is produced from fine-grained ore in order to provide a direct charge to the blast furnace. During the sinter production process fine sinter is produced that is not acceptable as feedstock for the blast furnace. This fine material is screened off and returned to the sinter plant to be recycled.
