Iron ore - Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron itself is usually found in the form of magnetite Fe 3O 4, 72.4% Fe, hematite Fe 2O Iron-ore mining methods vary by the type of ore being mined.
