a diagram of how iron ore is mined

  • Iron ore - Wikipedia

    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 ha2024年4月26日  Iron ore, a naturally occurring mineral composed primarily of iron oxides, is mined and processed to extract iron for various industrial applications. This article Iron Ore Processing: From Extraction to Manufacturing Mining 2023年5月7日  Mining and processing: Iron ore is typically mined through open-pit or underground mining methods, depending on the depth and location of the deposit. After extraction, iron ore is processed to remove Iron (Fe) Ore Minerals, Occurrence » Geology Science
