BAUXITE

Bauxite is a sedimentary rock group of various aluminium oxides, a principal ore of aluminium, found in France and Jamaica. Bauxite is often formed when aluminium-rich clays are carried away and deposited elsewhere. Bauxite was named after the place where it was first found, Les Baux in France. It has a relative hardness of 1 to 3.
