Last year, RTA s Weipa bauxite mine had a yield of 35 million tonnes, while 12.3 million tonnes came from Gove. Rio Tinto s 2020 fourth quarter production report details the activities of Gladstone refineries over the year. QAL produced 3.701 million tonnes of alumina in 2020, while Yarwun produced 3.175 million tonnes. Boyne Smelters Limited processed the alumina into 510,000 tonnes of aluminium in 2020. According to these figures, about 28 million tonnes of bauxite is needed to run the refineries at Yarwun and QAL. From this 28 million tonnes of bauxite, about 7 million tonnes of alumina is produced, which BSL could turn into 3.5 million tonnes of aluminium. If current production rates at Weipa and Gove are maintained, it is understood enough bauxite remains to continue refining at Yarwun and QAL for about 25 years.
