The aluminium-containing bauxite ores gibbsite, böhmite and diaspore are the basic raw material for primary aluminium production. Proven, economically viable reserves of bauxite are sufficient to supply at least another 100 years at current demand.
Bauxite and iron ores are rocks that are used to extract important metal elements and other minerals. They have different appearances and physical properties depending on the chemical composition. The main difference between bauxite and iron ore is that bauxite is a source of aluminum whereas iron ore is a source of iron.
