Bauxite mining - Norsk Hydro

How much does bauxite mining affect the environment? Because the bauxite is located close to the surface, mining disrupts the surface. Every year, the worldwide use of new land related to bauxite mining is 50 square kilometers. However, after the mining operations have been completed in one area, it is normally re-vegetated with local species.

Bayer process - Wikipedia

The Bayer process is the principal industrial, means of refining bauxite to produce alumina (aluminium oxide). Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to aluminium metal.
