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.
Its use in tools and weaponry did not surface until 1200 BCE when smelting, the process of extracting a metal from its ore by heating and melting it, made it a manageable material for metal workers to use.
