Jun 13, 2014 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.
Aug 26, 2019 Aluminum is the most abundant metal element in the Earths crust. Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it is a mixture of minerals, bauxite itself is a rock, not a mineral.
