Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides. Ores containing very high quantities of hematite or magnetite, typically greater than about 60% iron, are known as natural ore or direct shipping ore, and can be fed directly into iron-making blast furnaces.
