We mine bauxite in the South West of Australia and transport it on an overland conveyor belt to a refinery where the bauxite is turned into white alumina powder. The alumina is then exported to smelters around the world. As part of the Worsley Alumina operations, bauxite is mined near the town of Boddington, 130 kilometres (kms) south east of Perth. It is then transported on the largest overland conveyor belt in the southern hemisphere, for more than 50 kms, to a refinery near the town of Collie, where a 100-year-old process is used to turn the red bauxite rock into white alumina powder.
