  • Alumina Refining The Aluminum Association

    Alumina Refining. Quick Read. Alumina is the common name given to aluminum oxide (Al 2 O 3). Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite. To produce pure aluminum, alumina is smelted using the Hall–Héroult electrolytic ...

  • How aluminium is produced

    Alumina is the direct source of aluminium in the aluminium production process, but in order to create the right environment for electrolysis another component is necessary, and that component is cryolite. It's a rare natural fluoride mineral which due to its scarcity in natural form has been manufactured artificially. In modern metal production, cryolite is made by mixing hydrofluoric acid ...

  • Aluminium production process

    REDUCTION PROCESS At an aluminium smelter, alumina is poured into special reduction cells with molten cryolite at 950⁰С. Electric currents are then induced in the mixture at 400 kA or above; this current breaks the bond between the aluminium and oxygen atoms resulting in liquid aluminium settling at the bottom of the reduction cell. Casting. PRIMARY ALUMINIUM Primary aluminium is cast into ...

  • Mining and Refining – Process

    The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. Alumina refineries tend to be located close to bauxite mines and/or ports for efficient transport of raw materials and of the final ...
