Worsley Alumina

Interest in bauxite mining in the South West of Australia stretches back to the 1960s. However, mining and refining the ore didn't get underway until the 1980s. At the time, building the mine, conveyor belt and processing plant was Australia's most expensive capital project, costing AUD$1.2 billion and employing 3500 people.

Bauxite - Wikipedia

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium.Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH) 4) and small ...

Bauxite | The Aluminum Association

Bauxite ore, refined through two processes, is the primary source of aluminum. Land conservation is a key industry focus. An average of 80 percent of the land mined for bauxite is returned to its native ecosystem. Topsoil from the mining site is stored so it can be replaced during the rehabilitation process. Reserves will last for centuries.

Aluminium production process

ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.
