Bauxite deposits form close to the surface. Hence, all the mines in the world are open pit. About 8-14 tons of bauxite is needed to produce one ton of aluminum 1. So the ore of aluminum needs to be fairly rich in this metal to be worth mining. Aluminum is extracted solely from bauxite, but that does not mean that there are no alternatives.

Bauxite

The principal ore of aluminum is bauxite, a complex mixture of a number of aluminum hydroxides and hydrous aluminum oxides. The most common aluminum-bearing minerals in bauxite are gibbsite (AlOH3), boehmite (AlO(OH)), and diaspore (AlO(OH)). In the Arkansas deposits, diaspore has not been reported.
