iron ore mining hematite ore

  • Hematite: A primary ore of iron and a pigment mineral

    Hematite is the world’s most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in Metallic iron is virtually unknown on the surface of the Earth except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths. Some iron meteorites are thought to have originated from accreted bodies 1,000 km (620 mi) in diameter or larger. The origin of iron can be ultimately traced to its formation through nuclear fusion in stars, and most of the iron is thought to haIron ore - WikipediaThe most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe 2 O 3 ), which is red; magnetite (Fe 3 O 4 ), which is black; limonite or Iron processing - Ores, Smelting, Refining Britannica
