Aluminium | Geoscience Australia
Bauxite ore contains sufficiently high levels of aluminium oxides and suitably low levels of iron oxide (Fe 2 O 3) and silica (SiO 2) to be economically mineable. The amount of reactive silica is particularly important as this form of silica consumes the caustic soda needed to make alumina, thus low reactive silica is desirable.

Bauxite
Bauxite is the most common ore of aluminium. Extraction of aluminium metal takes place in three main stages: mining of bauxite ore, refining the ore to recover alumina, and smelting alumina to produce aluminium. Other raw materials are mined as aluminium ore, but their use is minor compared with bauxite. The only significant bauxite deposits …
