Dec 31, 2016 Most of the bauxite (~70%) was converted into alumina at Australia's six alumina refineries in Western Australia and Queensland, with the remainder exported as DSO with earnings of $985 million (Table 5). At 2016 levels of production, the average reserve life of operating mines is potentially 10 years and resource life could be 41 years (Table 2).
