• How Was Iron Made | Where Was Iron Found | DK Find Out

    Iron was found in rocks called iron ore. Making iron from iron ore (smelting) needed very high temperatures. Techniques for making iron were first developed in the Middle East, some time after 1550 BCE. Ironworking gradually spread westward, reaching Britain by 700 BCE. Iron was harder than bronze, which had been used to make objects before.

    Dec 18, 2018 · An iron alloy can only contain up to 2% carbon and still be called steel. If it contains more than 2% carbon, it's known as a different product called pig iron. Melting down iron ore with coke to create pig iron is an easy way of processing it, and is often an intermediate step in the refining process.

  • Iron Ore Statistics and Information

    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.
