Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation.
Reclamation. The bauxite and alumina companies rehabilitate minedout land by following a fourstep method. The minedout area is first reshaped and the topsoil that was first stripped off to prepare for mining is replaced. The area is then restored by planting the reclaimed area with pasture grasses, primarily to prevent erosion.
In October, 1943, Alcan was incorporated under the name Jamaica Bauxites Limited as a Jamaican company to investigate the commercial potential of Jamaican bauxite. In the same year, 2500 tonnes of ore was shipped to the USA for process investigation and it was realised that the bauxite was suitable for processing using Bayer technology.
The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production.
The Alcoa Bauxite Mine is near Bauxite, Arkansas. Historically the site has been part of the PulaskiSaline Mining District. The site was first discovered in 1887 by J. C. BrannerState Geologist. Production output of the Alcoa Bauxite Mine was considered to be medium size.
Australia is the largest producer of bauxite, followed by China. In 2017, China was the top producer of aluminium with almost half of the world''s production, followed by Russia, Canada, and India. Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries.

Handarm vibration syndrome seems to be rare in bauxite mining and alumina refining. Vibrating hand tools are not an important part of the process at bauxite mines, but are common at alumina refineries. Nevertheless, most bauxite mines and alumina refineries are located in tropical climates, so coldprovoked vasospasm is less likely.

When the land is cleared prior to mining, the topsoil is stored so it can be replaced during rehabilitation. During the stripmining process, bauxite is broken up and taken out of the mine to an alumina refinery. Once mining is complete, the topsoil is replaced and the area undergoes a restoration process.
