Aluminium smelting - Wikipedia

Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process.Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery.. This is an electrolytic process, so an aluminium smelter uses prodigious amounts of electricity; they tend to be located very close to large power stations, often hydro-electric ...

Alumina: Processes and Uses

Alumina is primarily derived from bauxite ore through the Bayer process, in which a caustic soda material, in combination with heat and pressure, is used to dissolve aluminum-bearing minerals from the bauxite. Bauxite residue is then separated from the sodium aluminate, allowing alumina to be crystallized from the remaining solution.

Bauxite: The principal ore of aluminum. - Geology

Bauxite Used for Aluminum Production. Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite.
