Aluminium ore, most commonly bauxite, is plentiful and occurs mainly in tropical and sub-tropical areas - Africa, West Indies, South America and Australia - with some deposits in Europe. Although plentiful, bauxite quality is diminishing, is often not readily accessible and is becoming harder to gain approvals for expansions or new mines.
