Iron ore - WikipediaIron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron itself is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite.iron ore mineral,Minerals | Iron OreThe pure metal is silvery white, very ductile, strongly magnetic and melts at 1528° C. Iron accounts for approximately 95% of all metals used by modern industrial society. Metallic iron is most commonly produced from the smelting of iron ore to produce pig iron.
USGS Minerals Information: Iron OreIron 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 (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world's iron and steel industries.

Iron is the third most common element making up the Earth. Iron is one of the three naturally magnetic elements; the others are cobalt and nickel. Iron is the most magnetic of the three. The principle ores of iron are hematite, (70% iron) and magnetite, (72% iron). Taconite is a low-grade iron ore, containing up to 30%.
