Bauxite | Mining, Refining, Alumina | Britannica
Bauxite is the principal ore of aluminum. Bauxites vary physically according to the origin and geologic history of their deposits: some deposits are soft, easily crushed, and structureless; some are hard, dense, and pisolitic, or pealike; still others are porous but strong or are stratified or largely pseudomorphic after their parent rock.

Aluminum – a light metal with a massive impact
Aluminum is extracted from bauxite in a complex chemical process. Producing one ton of raw aluminum results in up to four tons of toxic waste, which has a distinctive red color due to the iron-rich compounds it contains. This so-called red mud is stored in huge, open tailing ponds. Leaks and dam breaks are a frequent occurrence, often burying ...

Bauxite
The bulk of the world's bauxite production is processed into alumina (aluminum oxide) and then into aluminum. In the Bayer process, bauxites are heated in pressure vessels with sodium hydroxide solution at 150-200 °C. As a result, the aluminum in the ore is dissolved as aluminate, and the iron-rich residue (red mud) is separated by filtering.
