History

Alumina was founded in December 2002 when Western Mining Corporation spun off its aluminium and bauxite assets.<ref>Demerger effective following court appeal Western Mining Corporation 3 December 2002</ref>

Alumina's only business activity is as the owner of a 40% share in Alcoa World Alumina & Chemicals (AWAC), a joint venture with Alcoa. AWAC owns two bauxite mines and three refineries (to extract aluminium oxide from bauxite) in Western Australia and owns a smelter (to extract pure aluminium) and has a 55% interest in the Portland aluminium smelter. AWAC also operates and has interests in Brazil, Guinea, Saudi Arabia and Spain.<ref>Annual Report for year ended 31 December 2020 Alumina</ref>

In 2016, Alumina Limited achieved great short term authority over its interest in AWAC with more influence over a broader suite of operational and investment decisions.<ref>Alumina gets a win for the mouse that roared AFR 2 September 2016</ref>

Having been cross-listed on both the Australian Securities Exchange (ASX) and New York Stock Exchange (NYSE), Alumina delisted from the NYSE in February 2014, consolidating on the ASX.<ref>Alumina Limited Delisting Information Alumina</ref><ref>Alumina Limited to delist from NYSE Alumina 6 February 2014</ref>
