  • How aluminium is produced

    The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide - Al 2 O 3, - a white powderThe 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.

  • April 8,

    The Bayer process dissolves the aluminium component of bauxite ore in sodium hydroxide (caustic soda); removes impurities from the solution; and precipitates alumina tri hydrate, which is then calcined to aluminium oxide A Bayer Process plant is principally a device for heating and cooling a large re circulating stream of caustic soda solution.
