Iron is the fourth most abundant element in the Earth's crust, making up about 5% of it. It is primarily found in ores like hematite and magnetite. It is also present in the Earth's core in significant amounts. The extraction of iron is usually done through mining, followed by processes like smelting and refining to obtain the pure metal.

Carbon may also be left in the metal as an impurity. Sometimes this can be removed afterwards (for example, in the extraction of iron); sometimes it can't (for example in producing titanium), and a different method would have to be used in cases like this. Other more reactive metals can be used to reduce the ore.
