Worsley Alumina comprises a bauxite mine located near the town of Boddington and an Alumina refinery located near Worsley. Ore is mined then transport 50 km to the refinery via an overland conveyor system. Alumina is then transported 55 km to the port of Bunbury for shipping.[2]
390 redundancies were made in late February to reduce costs including long serving personal and those on maternity leave.[3]
Bauxite Mine
The Mount Saddleback bauxite mine is located in an area 10 km south of the town of Boddington, the orebody exists as a hardcap layer of between 2 and 12 meters thick, it is drilled and blasted before bulldozers can access the softer ore below. The ore is first crushed to a diameter less than 18 cm before a second stage reduces it to 3 cm.[4]
Alumina Refinery
The refinery uses a four-stage Bayer Process to transform the red bauxite rock into white alumina powder.
