Iron ore | BHP

What is iron ore? Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.

Iron Ore Statistics and Information - USGS

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 the world's iron and steel industries.

Iron Ore | Geoscience Australia

Iron Ore. Iron (Fe) is a metallic element which constitutes about 5% of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ).

Early History of Electricity and Magnetism

Steel is an alloy of iron with 0.5-1% of dissolved carbon.Since iron is extracted from its ores by heating it with carbon (much of which is burned away while heating the mix), the molten iron first emerging solidifies to cast iron with about 4% of carbon. Cast iron is strong but too hard to work and somewhat brittle, as its large hard crystals may break apart.
