About Alumina

Alumina Limited is engaged in bauxite mining, alumina refining, and aluminum smelting businesses worldwide. The company’s business activities are conducted through its 40% investment in AWAC (Alcoa World Alumina and Chemicals (Alcoa)). AWAC Operations Smelter-Grade Alumina and Primary Aluminium Australia In Australia, AWAC partners own 100% of AofA (Alcoa of Australia Limited), which operates integrated aluminium facilities, including mining, refining and smelting facilities. Alumina produced in Australia by AWAC is shipped either to its smelters at Point Henry and Portland in Victoria, Australia or to overseas AWAC customers, principally in South Africa, the Middle East, South East Asia, Russia, China, South America and North America. Bauxite is sourced from its 100% owned Huntly and Willowdale bauxite mines, each located in the Darling Ranges south of Perth, Western Australia, which supply AWAC’s three alumina refineries in Western Australia. The Pinjarra, Wagerup and Kwinana refineries have nameplate capacities of 4.2 million tonnes, 2.6 million tonnes and 2.2 million tonnes, respectively. AofA holds a 20% equity interest in a consortium that owns the Dampier to Bunbury Natural Gas Pipeline (DBNGP). This pipeline transports gas from the northwest gas fields to Alcoa’s alumina refineries and other users in the southwest of Western Australia. AofA uses gas to co-generate steam and electricity for its alumina refining processes at the Kwinana, Pinjarra and Wagerup refineries. AWAC produces primary aluminium in Victoria, Australia. The aluminium assets include an aluminium smelter at Point Henry, near Geelong, and a 55% controlling interest in an aluminium smelter at Portland, approximately 240 kilometres west of Geelong. The Portland smelter has an annual production capacity of 358,000 tonnes of aluminium and Point Henry has an annual capacity of 190,000 tonnes.
