The Chemistry and Processing of Jamaican Bauxite

 · 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.

Approximately 98% of the alumina produced worldwide is manufactured via the Bayer process, which consists of digestion and calcination. Initially, the bauxite is washed and ground. During digestion, the bauxite is dissolved in caustic soda (sodium hydroxide) at high pressure (40–220 bar) and at high temperature (120–300°C).
