Iron ore - Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known

Iron Ore - an overview | ScienceDirect Topics

Three potential sources (from the ores, sinter, or scrap) of naturally occurring radionuclides in the slag are discussed. Iron ores due to their geochemical properties scavenge radionuclides and heavy metals resulting in only trace levels of uranium in the main raw materials for iron-making; iron ore and coke ranging of 20–30 Bq/kg and 5 Bq/kg for limestone (Cooper, 2005).

Metal Profile: Iron Properties and Characteristics

Jan 12, 2020 · History . Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores.   The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.
