The process stages are: 1. Milling. The bauxite is washed and crushed, reducing the particle size and increasing the available surface area for the digestion stage. Lime and "spent liquor" (caustic soda returned from the precipitation stage) are added at the mills to make a pumpable slurry. 2.

Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite. To produce pure aluminum, alumina is smelted using the Hall–Héroult electrolytic process.

Bauxite is a high-aluminum-content rock. That is the main ore that aluminium is mined from. One of the most common elements on earth is bauxite. It contains almost 25 percent-30% alumina. In the belt around the equator, bauxite is commonly found. The primary aluminium bearing ore with an aluminium content of more than 35 to 40 percent is 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.

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). Thus, there is a
