Minerals and Ores Chemistry,

Ores: The minerals from which metals can be obtained on a commercial scale are called ores. In other words, the minerals from which metals can be extracted profitably are called ores. Both bauxite (Al 2 O 3 2H 2 O) and clay (Al 2 O 3 2SiO 2.2H 2 O) are minerals of aluminium. However, it is bauxite that is chiefly used to obtain aluminium .
