Extraction Process of Aluminium from Bauxite Ore
· 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.

How aluminium is produced
The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide Al 2 O 3, a white powder. The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today. About 90% of alumina refineries in the world use the Bayer process. It's very efficient but it can only be ...

Aluminium production process
ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.

Bauxite
During the process of bauxite production, the residue, called red mud, is separated and disposed in tailing pools. The residues from the bauxite production in Jamaica contain more than two times REEs (2000–3000 ppm), which are in particular, enriched in scandium (150 ppm) than the original bauxite ( Wagh and Pinnock, 1987 ).
