Iron ores are rocks and minerals from which metallic iron can be efficiently extracted. The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH).n(H2O)) or siderite (FeCO3). Hermatite is a type of iron concentrate obtained from pyrite. Detailed information including analyzes, pictures, and a video of concentrated iron ore is shared upon official request.
