Bauxite Extraction Process
Bauxite Mining Processing. Bauxite is the principal ore of alumina (Al2O3), which is used to produce aluminum. Bauxite is one of the most abundant elements on earth and contains nearly 25-30% of alumina. Its typically found near the equator in tropical and subtropical regions, in the form of horizontal layers beneath a few meters of overburden.
