Worsley Mine Development
Bauxite is mined near the town of Boddington, 130 kilometres south east of Perth. The bauxite is transported to the alumina refinery via an overland conveyor system that stretches more than 50 kilometres. The refinery extracts alumina using a four-stage Bayer process. This process turns the red bauxite rock into white alumina powder.
