Iron ores are usually purchased as fines or as pellets consisting mostly of iron oxide. Iron ore pellets are fed directly into the blastfurnace. Iron ore fines are mixed at the ironworks with limestone and other minerals and prefired at low temperatures to form a sinter agglomerates that can then be fed to the blastfurnace.
