bauxite and alumina processing

  • The Chemistry and Processing of Jamaican Bauxite

    The first commercial extraction of alumina (Al 2 O 3) from bauxite has been attributed to Henri Sainte-Claire Deville in about 1854.. Soon after this, in 1888, Karl Joseph Bayer described what is now known as the Bayer Process, which led to a dramatic reduction in the cost of aluminum metal.

  • Alumina | chemical compound | Britannica

    Alumina, also called aluminum oxide, synthetically produced aluminum oxide, Al 2 O 3, a white or nearly colourless crystalline substance that is used as a starting material for the smelting of aluminum metal.
