    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).

    By SCA Community Engagement Fellow Hayden Sloan. Aluminum (or Aluminium, if you’re not from the US) is an abundant element within Earth’s surface— but getting it out of the ground is an arduous process, requiring heavy machinery to plow up acres and acres of land.Fortunately, the environmental impact of that process can be somewhat balanced out by post-mining rehabilitation, efficient

    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 increase

  • Aluminium Geoscience Australia

    Mining. Extraction of aluminium metal takes place in three main stages¿mining of bauxite ore, refining the ore to recover alumina and smelting alumina to produce aluminium.
