Jan 07, 2018Bauxite 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.
