Jan 07, 2018· Bauxite is the primary feedstock for an alumina refinery to extract aluminium oxide using the Bayer process. Generally, around 2 to 3 tonnes of bauxite is required to produce one tonne of alumina. Aluminium metal is subsequently extracted from alumina in a smelter via electrolysis through the Hall-Heroult method.
Bauxite is primarily comprised of aluminum oxide compounds (alumina), silica, iron oxides and titanium dioxide. Approximately 70 percent of the world's bauxite production is refined through the Bayer chemical process into alumina. Alumina is then refined into pure aluminum metal through the Hall–Héroult electrolytic process. Mining bauxite
