Bauxite Technical Note What is bauxite? Hence, the major deposits are generally close to the surface. Bauxite is a mixture of aluminium minerals, clay minerals, and insoluble materials. Three aluminium minerals can occur in bauxite: gibbsite, boehmite and diaspore. Bauxite is the world's principal source of aluminium and can vary

bauxite mineral ore. As a result, not having direct and long-term access to high amounts of cheap electricity means no sustainable aluminium production however if you as an aluminium smelter don't have rich bauxite mines in your country, you can easily bring alumina in by importing from international markets. 3
