History and location

As part of the Worsley Alumina operations, bauxite is mined near the town of Boddington, 130 kilometres (kms) south east of Perth. It is then transported on the largest overland conveyor belt in the southern hemisphere, for more than 50 kms, to a refinery near the town of Collie, where a 100-year-old process is used to turn the red bauxite rock into white alumina powder.

The alumina is then transported by rail to Bunbury Port, where it is shipped to smelters around the world, including our 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.

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.
