Iron ores[1] 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.

Feb 3, 2022 · In this guide to iron ore, we explore the value of iron ore by understanding how this commodity plays a role in various industries and the global economy. Read on to learn about iron ore production, how iron ore is extracted and refined, and how it’s used in manufacturing as well as what experts say about the future of this commodity.
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 ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine.
