Bauxite Extraction Process — WORLDEQUITY

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.

TENORM: Bauxite and Alumina Production Wastes

2017-10-6  The Bayer Process. The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina.
