    How to extract aluminium from its ore The method The bauxite (red-brown solid) aluminium oxide mixed with impurities is extracted from the earth. The extracted aluminium oxide is then treated with alkali, to remove the impurities. This results in a white solid called aluminium oxide or alumina. The alumina is then transported to huge tanks.

  • Bauxite an overview ScienceDirect Topics

    Bauxite, the principal ore used for aluminum smelting, is named after Les Baux, Provence, the village where the first deposits were discovered. Bauxite contains hydrated alumina equivalent to as much as 40–60% Al 2 O 3, and is free of the other siliceous materials leached out over time. However it still contains 10–30% iron oxide, and some silica and other impurities, making it unsuitable

  • Bauxite an overview ScienceDirect Topics

    Bauxite ore is first mechanically pulverized and milled to reduce the particle size and then screened. The crushed ore is mixed with the process liquor containing caustic soda and processed in a grinding mill to produce a slurry containing 35–40% solids. Sodium hydroxide is the main chemical used in the process to extract aluminum hydrate from bauxite. Prior to digestion, the soluble silica
