Properties. In the Earth's crust iron is found mainly as minerals of iron oxide such as hematite, magnetite, goethite and limonite. The minerals that are mostly used as ore for making iron are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4).Iron is quite soft and easily worked, but it has a very high melting point of 1538°C.
