PROCESS DESCRIPTION: BAUXITE MINING. Bauxite is the principal ore of alumina (Al 2 O 3 ), which is used to produce aluminum (Al). It is composed of hydrated aluminum oxides, hydrated aluminosilicates, iron oxides, hydrated iron oxides, titanium oxide, and silica. It contains mixtures of various minerals such as gibbsite, boehmite, hematite ...


Malvern Panalytical' s predictive solutions help to efficiently sort and blend bauxite, ensure optimal and profitable extraction of available alumina, and support sustainable and safe waste management (red mud). Our expertise and solutions range from direct conveyor belt analysis to laboratory analysis and complete automated quality control.


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.
