Worsley Alumina

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.

Our operations

South32 owns 86 per cent of Worsley Alumina, with 10 per cent held by Japan Alumina Associates (Australia) Pty Ltd and the remaining 4 per cent held by Sojitz Alumina Pty Ltd.

Bauxite is mined near the town of Boddington, 130 kilometres south-east of Perth. It is transported by overland conveyor to the alumina refinery near Collie and turned into alumina powder, before being transported by rail to the Bunbury port.

It is then shipped to smelters around the world, including South32’s Hillside and Mozal aluminium smelters in Southern Africa.

Operations began in 1984 and today Worsley Alumina is recognised as one of the largest alumina refineries in the world.

Partnering with communities

Partnering with communities

As a major employer in the South West and Peel regions of Western Australia, our operations invest more than A$1 million each day into surrounding communities through wages, local businesses and community investment.

In FY22, we invested US$1.6 million in community projects around Worsley Alumina, with a focus on environmental protection and restoration, economic diversification and supporting education and cultural programs for Aboriginal and Torres Strait Islander Peoples.

Worsley Alumina also operates a Community Grants Program to provides grants of up to A$5,000 for local organisations, projects and programs that provide a benefit to people in South West communities.
