Cameco Corporation is the world's largest publicly traded uranium company, based in Saskatoon, Saskatchewan, Canada. In 2015, it was the world's second largest uranium producer, accounting for 18% of world production.
Uranium mining is the process of extraction of uranium ore from the ground. Over 50,000 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 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 and toxicity 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 234
U and 235
U than natural uranium.
The McArthur River Uranium Mine, in northern Saskatchewan, Canada, is the world's largest high-grade uranium deposit.
The Key Lake mine is a former uranium mine in Saskatchewan, Canada. It is 570 kilometres (350 mi) north of Saskatoon by air on the southern rim of the uranium-rich Athabasca Basin. Key Lake was initially developed to open-pit mine two nearby uranium ore deposits: the Gaertner deposit and the Deilmann deposit. Mining of this ore ceased in the late 1990s; the Key Lake mill now processes uranium ore from the McArthur River mine and from existing stockpiles on site. High-grade ore from McArthur river is blended with lower grade local rock before being passed through the mill. The mill has a permitted annual production capacity of 25 million pounds of U3O8. In addition, ammonium sulfate fertilizer is produced as a byproduct from used reagents. The pits of the mined out local deposits are being used as mill tailings management facilities.
Rabbit Lake is the second largest uranium milling facility in the western world, and is the longest-operating uranium production facility in Saskatchewan. The facility is located approximately 800 km north of Saskatoon, Saskatchewan, on the northeast edge of the uranium rich Athabasca Basin. The closest community is Wollaston Lake, about 40 kilometers by lake or air. Rabbit Lake was the first Canadian mine to offer a seven-days-in/seven-days-out commuter system of staffing. Access is provided by Highway 905. Production at Rabbit Lake was suspended in April 2016.
National Atomic Company Kazatomprom Joint Stock Company (Kazatomprom) (Kazakh: Қазатомөнеркәсіп, romanized: Qazatomónerkásip) is the world’s largest producer and seller of natural uranium, providing over 40% of global primary uranium supply in 2019 from its operations in Kazakhstan. Kazatomprom's uranium is used for the generation of nuclear power around the world.
Paladin Energy Ltd is a Western Australian based uranium production company.
Uranium mining in the United States produced 224,331 pounds (101.8 tonnes) of U3O8 in 2023, 15% of the 2018 production of 1,447,945 pounds (656.8 tonnes) of U3O8. The 2023 production represents 0.4% of the uranium fuel requirements of the US's nuclear power reactors for the year. Production came from five in-situ leaching plants, four in Wyoming (Nichols Ranch ISR Project, Lance Project, Lost Creek Project, and Smith Ranch-Highland Operation) and one in Nebraska (Crowe Butte Operation); and from the White Mesa conventional mill in Utah.
NMMC is the largest Uzbek industrial enterprise, is involved in the mining industry, and is one of the top ten largest gold producers in the world. The company's most important gold ore deposits are located in the Kyzyl Kum Desert.
The Cigar Lake Mine is a large high-grade underground uranium mine, located in the uranium-rich Athabasca Basin of northern Saskatchewan, Canada, at the south-west corner of Waterbury Lake. The deposit, discovered in 1981, is second in size of high-grade deposits only to the nearby McArthur River mine. Other deposits, such as the Olympic Dam mine in Australia, contain more uranium but at lower grades.
Uranium One is an international group of companies, part of the management circuit of the TENEX Group of Rosatom State Corporation. Since 2013, it is a wholly owned subsidiary of Moscow-based Uranium One Group, a part of the Russian state-owned nuclear corporation Rosatom.
Crow Butte is a uranium mining operation located four miles (6 km) southeast of the city of Crawford in Dawes County, Nebraska, United States. Cameco Corporation owns and operates Crow Butte through its wholly owned subsidiary, Crow Butte Resources, Inc.
Smith Ranch and Highland are uranium mining operations located in Wyoming, U.S.A. They are separate permits, operated as a single operation, and have one central processing facility. The Smith Ranch-Highland operation is the largest uranium production facility in the United States.
Atomredmetzoloto, JSC,, the Mining Division of Rosatom State Atomic Energy Corporation, is a Russian uranium producer internally ranked sixth in the world in terms of uranium production and second in terms of in-situ uranium reserves. ARMZ Uranium is the only uranium producer with operations inside Russia.
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.
The Yeelirrie uranium project is a uranium deposit located approximately 70 km southwest of Wiluna, in the Mid West region of Western Australia. The name Yeelirrie is taken from the local sheep station.
Uranium mining in Kazakhstan is of considerable importance to the national economy. By 2011, Kazakhstan was considered to be the world's largest producer of uranium.
The South Inkai mine is a large in-situ leaching mine located in the southern part of Kazakhstan in South Kazakhstan Province. South Inkai represents one of the largest uranium reserves in Kazakhstan having estimated reserves of 135.4 million tonnes of ore grading 0.026% uranium.
The Moiynkum Desert, is a desert in the Turkistan and Zhambyl regions of southern Kazakhstan.
