2022年1月1日 The three most common iron ore minerals are magnetite (Fe 3 O 4 ), hematite (Fe 2 O 3) and goethite (FeOOH), with the most common forms of goethite Metallic iron is virtually unknown on the surface of the Earth except as ironnickel 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 in diameter or larger The origin of iron can be ultimately traced to the formation through nuclear fusion in stars, and most of the iron is thought to have originatIron ore WikipediaThe most widely distributed ironbearing 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
