Iron ores are minerals from which metallic iron can be extracted. The iron itself is usually found in the form of magnetite[?] (Fe 3 O 4) or hematite (Fe 2 O 3), both of which are iron oxides.However, as much of the pure magnetite and hematite ore has already been mined, modern iron mines rely on aggregate minerals such as taconite[?], which must be processed to remove non-iron …
