Bauxite

Aluminum ore, called bauxite, is most commonly formed in deeply weathered rocks. In some locations, deeply weather volcanic rocks, usually basalt, form bauxite deposits. This sample of bauxite ore is from Western Australia. Uses for Aluminum Aluminum has a wide range of common uses. It is lightweight, strong (especially with alloys), and conducts heat well.
