  • Guide to bauxite, alumina and aluminium what you need to

    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 to aluminium Boyne Smelters,The process of making aluminium starts with the mining of bauxite.
