Uranium mining in Australia

Résumé

Radioactive ores were first extracted in South Australia at Radium Hill in 1906 and Mount Painter in 1911. 2,000 tons of ore were treated to recover radium for medical use. Several hundred kilograms of uranium were also produced for use in ceramic glazes. In 2019 Australia exported of uranium, 12% of world production, for use in nuclear power generation. IAEA and the OECD's NEA reported that the price of uranium in 2019 was $130/kg, and estimated that 35% of the world's uranium resource reserves was in Australia (1,748,100 tonnes out of 4,971,400 tonnes). In terms of production, Kazakhstan is the largest supplier, followed by Canada and Australia. Following the Japanese Fukushima nuclear disaster in early 2011, many countries scaled back their nuclear power production, with some setting deadlines for a complete shutdown of all nuclear power reactors, with a resultant impact on demand for uranium. As of 2013 uranium prices have been very low. New mine developments have received State government approval in Western Australia and Queensland, although it is unlikely that new projects will enter active development until the uranium market price improves. For several decades uranium mining has been a major part of the Australian political discussion, with opposition groups citing the wide-ranging environmental impacts, indigenous land access and nuclear proliferation as reasons for ceasing or restricting the industry. The debate has resulted in limitations on mining and export activities, with Federal and State governments occasionally backflipping on public policy. As of 2017, there were three operational uranium mine sites: Olympic Dam (BHP), Ranger (Energy Resources of Australia), and Beverley Four Mile (Heathgate Resources). The occurrence of uranium in Australia had been known since the 1890s. Uranium was produced as a bi-product of radium mining in South Australia at Radium Hill from 1906 and Mount Painter from 1911. A refinery at Hunters Hill, Sydney processed the ore between 1911 and 1915 for radium bromide and uranium.
