  • Aluminium production process

    This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda. Aluminium oxide appears in the resulting slurry while all the admixtures settle to the bottom as red mud.

  • Alumina Refining | The Australian Aluminium Council

    The precipitated material (called hydrate) is washed and dried at temperatures exceeding 1000 degrees Celsius. This forms the dry white anhydrous aluminium oxide powder (alumina) which is cooled and conveyed to storage. The caustic soda is recovered and returned to the start of the process …

  • Chapter 2. Production and Processing of Aluminum

    The starting material for electrolytic smelting of aluminum is pure, anhydrous alumi-num oxide (Al 2 O 3) called alumina. In the Western World, the Bayer 1 process, invented in the 19th century, is by far the most important process used in the production of alumi-num oxide from bauxite. The process has been refined and improved since its inception.
