History and location

South32 holds an 86 per cent interest in Worsley Alumina, while Japan Alumina Associates (Australia) Pty Ltd owns 10 per cent and Sojitz Alumina Pty Ltd owns four per cent.

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

A rich history

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.

Over the past three decades our production has increased four-fold, making Worsley Alumina one of the largest and lowest-cost alumina producers in the world.

Bauxite

Improving water efficiency

We've been largely self-sufficient in water use for production purposes for thirty years. But with an ongoing drying trend affecting the region we know we need to do more to enhance water efficiency and secure our water supplies.

Playing our part

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

Minimising diesel exhaust emissions

We've developed new technology to monitor and reduce diesel exhaust emissions at our underground mines.

Building the skills of the future

We're supporting local youth coding clubs in the South West of Western Australia.

Inspiring the next generation

We're giving school students an opportunity to get real experience in our operations.
