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 (Fe3O4, 72.4% Fe), hematite
(Fe2O3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite
(FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe).
