Alcoa of Australia - Huntly


Phone: +61 8 9530 2400 

Website: Alcoa Mining

The Huntly mine is located near Dwellingup and was established in early 1976. Huntly is the world’s largest bauxite mine, supplying bauxite ore to Pinjarra and Kwinana Refineries. Huntly bauxite production has doubled since 1990 and currently produces around 23 million tonnes of bauxite per year.

The Huntly mine and the Willowdale mine make up Alcoa of Australia Mining. The ore from Huntly and Willowdale is refined to produce about 10 million tonnes of alumina each year. This represents around 45% of Australia’s alumina production and 30% of aluminium production. Alumina production from Alcoa’s WA refineries accounts for 11% of total world demand.

For both the Huntly and Willowdale mines, rehabilitation is one of the most important parts of the mining process. Every year about 600 hectares of the mined areas are rehabilitated across the two sites, helping restore the jarrah forest ecosystem.

Across Alcoa’s Australian operations, there are currently over 6000 people employed directly, with approximately 850 employed in the WA mining operations.

Each year, more than 75% of Alcoa's total revenue stays in Australia through wages, local suppliers, royalties, taxes, rates and dividends.
