    iron ores are less rich and have a large number of impurities. The most important iron ore-forming minerals are: • Magnetite Magnetite (Fe3O4) forms magnetic black iron ore. There are large deposits of magnetite in Russia and Sweden. • Hematite Hematite (Fe2O3) is a red iron ore. Hematite occurs in almost all forms, fromIron processing Ores Britannica,Iron processing Iron processing Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine.
