  • Bayer Process

    In an alumina refinery bauxite is processed into pure aluminium oxide (alumina, or Al 2 O 3), which is the main raw material required for production of primary aluminium The Bayer process extracts alumina by caustic digestion of crushed bauxite at high temperature and pressure in an autoclave, followed by clarification, precipitation, washing ....

  • Aluminium smelting

    Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult processAlumina 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 huge amounts of electricity; smelters tend to be located close to large power stations, often hydro-electric ones ....

  • 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...
