  • Iron Ore Statistics and Information U.S. Geological Survey

    Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for 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 - Wikipedia2022年1月1日  Characteristics of ten of the world’s metallogenic provinces hosting iron oxide Cu-Au (IOCG) deposits have been critically assessed, including their geological Iron oxide copper-gold (IOCG) deposits - ScienceDirect

    2014年3月1日  Submarine volcanogenic iron oxide (SVIO) deposits are one of the most important sources of high-grade iron ores in China. The spatial distribution of the Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by Iron processing - Ores, Smelting, Refining BritannicaSedimentary iron deposits, from which almost all iron is obtained, can therefore be viewed as one of the world’s great mineral treasures. There are two major types of deposit. The Mineral deposit - Iron Ore, Ore Bodies, Mining Britannica
