The Chemistry and Processing of Jamaican Bauxite

The Chemistry of Bauxite and Alumina 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.
