Bauxite Processing Residue: A Critical Review of

Bauxite is processed in alumina refineries by the Bayer process in which Al-containing minerals are dissolved in hot NaOH. The insoluble solids (bauxite processing residue mud and sand) are washed, sometimes partially neutralized (using CO2 or seawater treatment), and deposited in impoundments surrounding the refinery using either wet (15–30% solids) or dry (50–65% solids) disposal techniques.

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.

Bauxite in Jamaica - Geo for CXC

Bauxite is the ore from which aluminium is made. Jamaica contains some of the largest known deposits of bauxite in the world. The mining areas are located in the western and central parts of the island. After mining, most of the bauxite is carried to alumina plants where it is refined into alumina. The alumina (or in some cases unrefined

Extraction Process of Aluminium from Bauxite

In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch. However, some lateritic bauxite ores are readily soluble in caustic, making it possible for them to be leached, or "digested," at atmospheric pressure.
