  • Aluminium production process

    The pure form of aluminium does not naturally occur in nature, so remained largely unknown until as recently as 200 years ago. Creating aluminium using electricity was first developed in 1886 and is still used to this day. The aluminium production process starts with the mining of bauxites, an aluminium rich mineral in in the

    OverviewFormationProduction trendsProcessingSource of galliumSee alsoFurther readingExternal links

    Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2).

    The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide Al 2 O 3, a white powder.The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today.

  • The Chemistry and Processing of Jamaican Bauxite

    In October, 1943, Alcan was incorporated under the name Jamaica Bauxites Limited as a Jamaican company to investigate the commercial potential of Jamaican bauxite. In the same year, 2500 tonnes of ore was shipped to the USA for process investigation and it was realised that the bauxite was suitable for processing using Bayer technology.

    Aluminum, or aluminium (Al), is a silvery white metal with a melting point of 660 °C (1,220 °F) and a density of 2.7 grams per cubic cm. The most abundant metallic element, it constitutes 8.1 percent of Earth’s crust. In nature it occurs chemically combined with oxygen and other elements. In the pure state it is soft and ductile, but it can be alloyed with many other elements to

    The Bayer Process. The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina.
