Iron Ore is a type of rock that contains iron minerals, mainly hematite and magnetite. It is a vital raw material for the production of steel. The ores are rich in iron oxides, which range in colour from dark grey to bright yellow to deep purple to rusty red. The most common iron minerals are magnetite, hematite, goethite, limonite, and siderite.
