Mining and Refining Process World Aluminium

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.

Bauxite Mining Process Analytical Solutions Malvern

Bauxite Mining Prior to extracting bauxite ore, deposits must be evaluated to gain knowledge about the grade distribution within an ore body to optimize mine planning. Malvern Panalytical’s analytical solutions enable grade definition directly in the field with mineralogical (NIR) and elemental (XRF) analyzers.

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
