Aluminum is extracted from bauxite ore by way of the Bayer process. This requires a great deal of electricity; consequently, a large amount of aluminum is processed in Iceland, which gets its electricity through geothermal energy. To extract aluminum, the bauxite ore is first crushed, then mixed with lime, hot water and soda ash.

Two of the most common compounds are alum, such as potassium aluminum sulfate (KAl(SO 4) 2 ·12H 2 O), and aluminum oxide (Al 2 O 3). About 8.2% of the earth's crust is composed of aluminum. Scientists suspected than an unknown metal existed in alum as early as 1787, but they did not have a way to extract it until 1825.
The method used to extract metals from the ore in which they are found depends on their reactivity. For example, reactive metals such as aluminium are extracted by electrolysis, while a less-reactive metal such as iron may be extracted by reduction with carbon or carbon monoxide.
