Raw iron ore is characterized by the most abundant iron-containing mineral found in the ore: magnetite (Fe 3 O 4), hematite (Fe 2 O 3), siderites (FeCO 3), and limonites (2Fe 2 O 3 ·3H 2 O) (Walker, 1986). All the impurities in iron ore (silica, alumina, titania, sulfur, and phosphorus) are collectively known as gangue.
