Nuclear Industry In South Australia
The nuclear industry in South Australia is focused on uranium mining, milling and the export of uranium oxide concentrate for use in the production of nuclear fuel for nuclear power plants. The state is home to the world's largest known single deposit of uranium, which is worked by BHP at the Olympic Dam mine. Contaminated legacy sites exist at Maralinga and Emu Field, where nuclear weapons tests were conducted in the 1950s and 1960s; and at former uranium mines and milling sites. Nuclear waste is also stored by the CSIRO at Woomera. In 2016, the Nuclear Fuel Cycle Royal Commission recommended that South Australia consider establishing a facility for nuclear waste storage (including developing a repository for spent nuclear fuel) and repealing prohibitions which currently prevent future nuclear industrial development nationally. In 2017, a site near Kimba on Eyre Peninsula was selected for Australia's national radioactive waste management facility, where domestically-generated ...

Uranium Mining
Uranium mining is the process of extraction of uranium ore from the ground. Over 50 thousand tons of uranium were produced in 2019. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% of world production. Other countries producing more than 1,000 tons per year included Namibia, Niger, Russia, Uzbekistan, the United States, and China. Nearly all of the world's mined uranium is used to power nuclear power plants. Historically uranium was also used in applications such as uranium glass or ferrouranium but those applications have declined due to the radioactivity of uranium and are nowadays mostly supplied with a plentiful cheap supply of depleted uranium which is also used in uranium ammunition. In addition to being cheaper, depleted uranium is also less radioactive due to a lower content of short-lived and than natural uranium. Uranium is mined by in-situ leaching (57% of world production) or by conventional und ...

Mount Gee
Mount Gee is located in the northern Flinders Ranges within the Arkaroola Wilderness Sanctuary, and is part of the Mount Painter inlier. It was named after a mining warden, Lionel Gee. Recently Mount Gee came to prominence in 2008–2011 because of uranium exploration occurring in an area that was commonly (and mistakenly) believed at that time to be protected from all mineral exploration. This situation was altered in 2011–2012 when the Government of South Australia created the Arkaroola Protection Zone and passed the Arkaroola Protection Act (2012) which prohibits all mining activity in the Arkaroola Protection Zone. Geography With its peak rising 600 metres above sea level Mount Gee is one of several peaks located in the visually spectacular and geologically significant range north-east of the Gammon Ranges and south of the Mawson Plateau. Mount Gee was entered on the Register of the National Estate in 1982 due to its "spectacular mass of quartz crystal and vughul ...

Nuclear Non-Proliferation Treaty/Treaty Text
The Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT, is an international treaty whose objective is to prevent the spread of nuclear weapons and weapons technology, to promote cooperation in the peaceful uses of nuclear energy, and to further the goal of achieving nuclear disarmament and general and complete disarmament. Between 1965 and 1968, the treaty was negotiated by the Eighteen Nation Committee on Disarmament, a United Nations-sponsored organization based in Geneva, Switzerland. Opened for signature in 1968, the treaty entered into force in 1970. As required by the text, after twenty-five years, NPT Parties met in May 1995 and agreed to extend the treaty indefinitely. More countries are parties to the NPT than any other arms limitation and disarmament agreement, a testament to the treaty's significance. As of August 2016, 191 states have become parties to the treaty, though North Korea, which acceded in 1985 but nev ...

Fukushima Daiichi Nuclear Disaster
The was a nuclear accident in 2011 at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan. The proximate cause of the disaster was the 2011 Tōhoku earthquake and tsunami, which occurred on the afternoon of 11 March 2011 and remains the most powerful earthquake ever recorded in Japan. The earthquake triggered a powerful tsunami, with 13–14-meter-high waves damaging the nuclear power plant's emergency diesel generators, leading to a loss of electric power. The result was the most severe nuclear accident since the Chernobyl disaster in 1986, classified as level seven on the International Nuclear Event Scale (INES) after initially being classified as level five, and thus joining Chernobyl as the only other accident to receive such classification. While the 1957 explosion at the Mayak facility was the second worst by radioactivity released, the INES ranks incidents by impact on population, so Chernobyl (335,000 people evacuated) and Fukushima (154,000 evacuate ...

Honeymoon Uranium Mine
The Honeymoon Mine was Australia's second operating in-situ recovery uranium mine, beginning production in 2011. It is located in South Australia and is northwest of Broken Hill, New South Wales. Honeymoon is a sandstone-hosted paleochannel deposit. Operations at Honeymoon were suspended in November 2013, following difficulties in reaching production targets, high costs and a falling uranium price. The project was placed in care and maintenance, then sold by Uranium One (a 100% subsidiary of Rosatom State Atomic Energy Corporation) to Boss Resources and Wattle Mining (as of March 2018 a subsidiary of Boss) in September 2015 for a sum of A$9 million. Boss Resources anticipates resuming production at the mine in 2019. History The Honeymoon deposit was discovered in 1972 by a joint venture (Minad-Teton-CEC JV) between Mines Administration (a subsidiary of CSR Limited), Carpentaria Exploration (subsidiary of Mount Isa Mines) and Teton Exploration Drilling Co (subsidiary of Uni ...

Beverley Uranium Mine
The Beverley Mine is Australia's third uranium mine and Australia's first operating in-situ recovery mine. It is located in South Australia in the gazetted locality of Wooltana about 35 km from Lake Frome at the northern end of the Flinders Ranges. It officially opened in 2001. The original Beverley uranium deposit was discovered by one of Bill Siller's companies in 1969 and was named after his wife—Beverley Siller. The mine is owned and operated by Adelaide-based company Heathgate Resources Pty Ltd. Heathgate Resources is a wholly owned subsidiary of General Atomics. Beverley is a palaeochannel uranium deposit. The uranium mineralisation (mainly coffinite) is hosted by loose sands in the channel of a former river. The ore bearing horizon is now at a depth of about 100 to 150m. The deposit is estimated to contain 21,000 tonnes of uranium oxide for a mine life of 15 to 30 years. Uranium is extracted by in-situ leaching, involving the injection of a fluid containing ...

In Situ Leach
In-situ leaching (ISL), also called in-situ recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, ''in situ''. In situ leach works by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see: Brine mining. The process initially involves the drilling of holes into the ore deposit. Explosive or pathways in the deposit for solution to penetrate. Leaching solution is pumped into the deposit where it makes contact with the ore. The solution bearing the dissolved ore content is then pumped to the surface and processed. This process allows the extraction of metals and salts from an ore body without the need for conventional mining involving drill-and-blast, open-cut or underground mining. Process In-situ leach mining involves pumping of a lixiviant into the ore body via a borehole, which circulates through the porous ...

Iron Oxide Copper Gold Ore Deposits
Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million to >4,000 million tonnes of contained ore, and have a grade of between 0.2% and 5% copper, with gold contents ranging from 0.1 to 1.41 grams per tonne. These ore bodies tend to express as cone-like, blanket-like breccia sheets within granitic margins, or as long ribbon-like breccia or massive iron oxide deposits within faults or shears. The tremendous size, relatively simple metallurgy and relatively high grade of IOCG deposits can produce extremely profitable mines, although the formation of these deposits is still not fully understood, and the fluid origin of the world class deposits are still being investigated. Iron oxide copper-gold deposits are also often associated with other valuable trace elements such as uranium ...
