Mining and Refining Responsible Sourcing

Bauxite mining consumes a relatively small amount of energy (and consequently has low greenhouse gas emissions) compared to alumina refining and aluminium smelting processes. Diesel fuel and fuel oil combustion provides the bulk (95%) of the energy required to extract and haul the mined ore.

Mining and Refining Process

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which include washing, wet screening and mechanical or manual sorting.
