An ore is a type of rock containing compounds from which metals can be extracted. Ores are typically metal oxides or a compound of a metal that can be converted to an oxide. For example, the main aluminium ore is called bauxite which is aluminium oxide (Al 2 O 3). The metal is removed from the oxide in a process called reduction.
