Sustainable Bauxite Mining
About 90% of global bauxite supplies are found in tropical and subtropical areas, with 73% found in just five countries: Guinea, Brazil, Jamaica, Australia and India. Guinea has the largest supply of bauxites with 5.3 billion tonnes (28.4% of the total global supply).
The aluminium production process can be broken down into three stages; first bauxites, which contain aluminium, are extracted from the ground. Second, bauxites are processed into alumina or aluminium oxide, and finally in stage three, pure aluminium is produced using electrolytic reduction, a process in which aluminium oxide is broken down into its components using electric current.
The aluminium industry’s objective is a long-term, sustainable bauxite mining industry with acceptably low social and environmental impacts during operation and post-closure. Sustainable bauxite mining is not a “one-size fits all” prescriptive process but involves risk management and applying technologies appropriate to the circumstances of each mine.
