What is iron ore? Iron ores are rocks and minerals rich in iron oxide that can produce metallic iron when smelted. Due to the nature of the iron oxide present in iron ore, they can range in color from dark grey to a deep red. The iron in such ores is commonly found in the form of magnetite, hematite, goethite, limonite, and siderite.
