The Chemistry and Processing of Jamaican Bauxite The first commercial extraction of alumina Al 2 O 3 from bauxite has been attributed to Henri SainteClaire 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
