Australia produced 53.0 Mt bauxite and 16.5 Mt of alumina and 1.9 Mt of aluminium in 2003. This represented 40% of the western world’s production output. Australia has emerged also the world’s major alumina producer. In 2003 it accounted for 36% of Western output of 46.3Mt. The most significant deposits of bauxite in Australia are located at Weipa in northern Queensland, at Gove on the Gove Peninsula in Northern Territory, and in the Darling Range and Mitchell Plateau areas of Western Australia. Deposits at Mitchell Plateau and Cape Bougainville in the north of Western Australia are uneconomic to develop but are important as future resources. All of Australia’s bauxite deposits are hosted by aluminium rich laterites, with Gibbsite being the main ore bearing aluminium mineral. The australian aluminium and bauxite industry consists of five bauxite mines, six alumina refineries, six primary aluminum smelters, twelve extusion mills and four rolled product mills.
The four main producers in Australia are:
Alcoa World Alumina & Chemicals (AWAC) operates the Huntley mine, one of the largest in the world. AWAC is owned by Alcoa Inc. 60% and WMC 40% and operates as Alcoa of Australia. Huntley is situated in Western Australia 80km south of Perth. Has indicated reserves of 700 Mt. The mine has a capacity to produce 18Mt per year. Alcoa also operates the Willowdale Mine situated 130km south of Perth in Western Australia. In 2003, the refineries produced approximately 7.9 Mt of alumina and the smelters a record 545,000 t of aluminium.
Worsley – The Worsley smelting and refining complex sources ore from the nearby Mount Saddleback mine south of Perth with estimated reserves of 400 Mt. Worsley is owned by Billiton 86% and Japanese Kobe 10%
In 2000 Alcan acquired the remaining 70% of the Gove bauxite deposit and refinery situated in northern Territories. Additional ore is being sourced from the nearby Rocky Bay deposit, which will extend the life of mine to 2030. In late 2003, Alcan Gove Pty Ltd completed an Environmental Impact Statement (EIS) for its proposed A$1.5 billion expansion of the Gove alumina refinery in the Northern Territory. The expansion would increase alumina production capacity from 2 Mt/y to around 3.5 Mt/y and convert all of Alcan Goves bauxite output into alumina.
In 2003 expansion of the Weipa bauxite mine in Queensland commenced, with intentions to increase production capacity to 16.5 Mt/y, mostly to supply the new Comalco alumina refinery. Construction of the US$750 million facility at Gladstone, Qld, is on schedule and initial shipments from the 1.4 Mt/y plant are expected in 2005. In June 2003, Norsk Hydro signed a longterm supply agreement with Comalco to buy 500,000 t/y of alumina for more than 20 years to feed its aluminium smelters in Australia and elsewhere.
