Sep 05, 2012 Potential radiological impacts from mining and processing are mainly due to the radiation associated with radionuclides 232 Th and 238 U and their decay products, and there is a relatively small, essentially negligible, contribution to radiation dose estimates from 40 K in the bauxite. The approximate K chemical concentration of 0.2 wt % in bauxite ore corresponds to a K-40 activity of 0.062

Mining. Bauxite is mined from reserves mainly within State forest on the eastern edge of the Darling Range, near Boddington. The bauxite is crushed and carried 51km by a two-flight cable belt conveyor system to the refinery site at Worsley. It is then processed, and the separated alumina is carted by rail and exported through the Port of Bunbury.

Bauxite is the main commercial mineral from which aluminium oxide is extracted, which in turn is smelted to form aluminium metal. Typically, a bauxite resource contains 30-60% alumina (Al 2 O 3 ), and occurs as two main types: trihydrate (“low temperature”) bauxite and monohydrate (“high temperature”) bauxite.
