  • Alumina Refining The Australian Aluminium Council

    Alumina Refining Alumina is a white granular material a little finer than table salt and is properly called aluminium oxide. Aluminium does not occur as a metal but must first be refined from bauxite into alumina. Approximately two tonnes of alumina are required to produce one tonne of aluminium.

  • Aluminium RecyclingProcesses

    Energy is consumed throughout the refining process. The transformation of scrap into recycled aluminium alloys requires approximately 5 of the energy input needed to produce primary ingot from bauxite. Depending on the impurities in the scrap various air emissions may be generated such as organic compounds and dust.
