What Is the Bayer Process? (with picture)

The Bayer process is an industrial process by which bauxite is purified into alumina, or aluminum oxide. Named for Karl Bayer, who developed it in the late 19 th century, this process is an essential intermediate step in the production of aluminum metal. Alumina is produced through a series of controlled chemical reactions from bauxite, a ...

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.

Bayer Process

The Bayer process is basically used for the extraction of aluminum hydrate from the bauxite ores with the mass ratio of alumina to silica (A/S) above 9. The sinter process is widely used to process the poor-grade diasporic bauxite ores with A/S below 7, in China and Russia, by sintering the bauxite ore with sodium carbonate and limestone to form sodium aluminate and calcium silicate.
