The bauxite mines in the Darling Range have the world's lowest grade bauxite ore mined on a commercial scale (around 27-30% Al 2 O 3). Despite the low grade, the mines accounted for 23% of global alumina production.
Australia is the world's largest producer of bauxite and a significant global supplier of high value downstream products, including refined alumina and smelted aluminium metal.
The largest producer is Australia's Weipa Mine in northern Queensland, while other countries with large reserves include Guinea, Vietnam, and Jamaica. Formed in a similar manner to iron laterites, bauxite is created by weathering of suitable rocks in a tropical climate.
It includes the Huntly mine in Australia, the second largest bauxite mine in the world. Alcoa offers bauxite from its mines to meet customer-specific needs and provide a consistent, reliable, and sustainable supply of raw material for refineries around the globe.

Rio Tinto mines bauxite from its Weipa mine in Queensland and the Gove project in the Northern Territory. Gove and Weipa are among the world's highest grade bauxite deposits, with average grades of between 49% and 53% alumina, according to Geoscience Australia.
Once the bauxite is loosened into manageable pieces it is generally loaded into trucks, railroad cars or conveyors and transported to crushing and washing plants or to stockpiles, before being shipped to alumina refineries, which are generally located close to bauxite mines.
The bauxite trade was dominated by a few large mines, including Gove and Weipa in Australia, Boke in Guinea and Trombetas in Brazil. This has changed with the rise of China since 2001. It is estimated that the seaborne trade now comprises 35% of global bauxite production of …
Operations • Huntly mine is the world's second largest bauxite mine, supplying ore to Pinjarra and Kwinana alumina refineries. It was established in 1976 and is located near Dwellingup in Western Australia.
There are currently five bauxite mines in Australia providing feedstock for the seven alumina refineries, which in turn supply alumina to the six Australian aluminium smelters and the export market.
Bauxite mining and aluminium smelting in Australia are major contributors to world supplies of aluminium. Australia mainly exports bauxite to India and China.
