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 the world's iron and steel industries.

Iron
About 98% of world iron ore production is used to make iron in the form of steel. Iron in cast form has many specific uses (e.g. pipes, fittings, engine blocks) but pure iron is quite soft. Adding a small amount of carbon (usually less than 1%) makes iron into steel which is significantly harder and extremely versatile.

Iron Ore
Pig iron is an intermediate step in the production of steel and is produced by smelting iron ore (commonly in lump, pellet or sinter form) in blast furnaces. The removal, by oxidation, of impurities in pig iron such as silicon, phosphorus and sulfur and the reduction in the carbon content, results in the production of steel.
