bauxite process continues from mining to alumina

Guide to bauxite, alumina and aluminium what you

Alumina aluminium oxide Al2O3, is the key input in producing aluminium metal. Itmonly manufactured as a white granular powder, and is extracted from bauxite in a refinery using the Bayer process. Around 90 of world alumina supply is used to produce primary aluminium metal via the Hall Heroult process.
