Rio Tinto Group is a British-Australian multinational company that is the world's second largest metals and mining corporation. It was founded in 1873 when a group of investors purchased a mine complex on the Rio Tinto, in Huelva, Spain, from the Spanish government. It has grown through a long series of mergers and acquisitions. Although primarily focused on extraction of minerals, it also has significant operations in refining, particularly the refining of bauxite and iron ore. It has joint head offices in London, England and Melbourne, Australia.
Gilbert A. LaBine, was a Canadian prospector who, in 1930, discovered radium and uranium deposits at Port Radium, Northwest Territories. LaBine was president of Eldorado Gold Mines from its start in the late 1920s to 1947. He left the company, which had become a Crown corporation in 1944, to prospect for uranium minerals as an independent mine developer. In the 1950s he brought the Gunnar Mine to production at Uranium City, Saskatchewan.
The Rayrock Mine was a uranium producing venture in the Northwest Territories, Canada. It is located on the south side of Maryleer Lake and the north shore of Fault Lake, 169 kilometers northwest of Yellowknife and 74 kilometres northwest of Rae. Radioactive deposits were originally staked in 1948 and then restaked in 1950. American Yellowknife Mines Limited explored the site with detailed Geiger surveys and extensive trenching in the early 1950s. In 1954 exploration work included over 10,000 feet (3,000 m) of surface diamond drilling, and the company was reorganized as Rayrock Mines Limited.
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, 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 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.
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.
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.
The Quirke Mine is an abandoned uranium mine located approximately 13.5 km north of Elliot Lake, Ontario, owned and operated by Rio Algom Ltd. The site has been rehabilitated and is currently undergoing environmental monitoring.
The Pronto Mine is an historical uranium mine located approximately 20 km south of Elliot Lake, Ontario near Spragge. The site is owned and operated by Rio Algom Ltd, has been rehabilitated and is currently undergoing environmental monitoring.
The Can-Met Mine is an abandoned uranium mine located approximately 12.5 km northeast of Elliot Lake, Ontario, owned by Denison Mines Ltd. The site has been rehabilitated and its tailings facility is currently undergoing environmental monitoring by Denison Environmental Services.
Consolidated Denison Mine, or the Denison Mine is an abandoned uranium mine located approximately 12.5 km north of Elliot Lake, Ontario. The site is bordered north by Quirke Mine and New Quirke Mine; on the east by Panel Mine and Can-Met Mine; and south by Spanish American Mine and Stanrock Mine.
Four Mile is Australia's fifth uranium mine. It is sited in the Frome Basin in far north of the state of South Australia, around 600 kilometres (370 mi) north of the state capital, Adelaide. It is 10 kilometres (6 mi) from the existing Beverley uranium mine, where its uranium oxide product is produced. Construction of the mine commenced in late 2013 and the mine was officially opened in June 2014.
Silver Reef is a ghost town in Washington County, Utah, United States, about 15 miles (24 km) northeast of St. George and 1 mile (1.6 km) west of Leeds. Silver Reef was established after John Kemple, a prospector from Nevada, discovered a vein of silver in a sandstone formation in 1866. At first, geologists were uncertain about Kemple's find because silver is not usually found in sandstone. In 1875, two bankers from Salt Lake City sent William Barbee to the site to stake mining claims. He staked 21 claims, and an influx of miners came to work Barbee's claims and to stake their own. To accommodate the miners, Barbee established a town called Bonanza City. Property values there were high, so several miners settled on a ridge to the north of it and named their settlement Rockpile. The town was renamed Silver Reef after silver mines in nearby Pioche closed and businessmen arrived.
The relationship between Uranium mining and the Navajo people began in 1944 in northeastern Arizona, northwestern New Mexico, and southeastern Utah.
The Langer Heinrich Mine (LHM) is a large open pit mine located in the western part of Namibia in the Erongo Region. Langer Heinrich represents one of the largest uranium reserves in Namibia having estimated reserves of 57,000 tonnes of ore grading 0.055% uranium. The Langer Heinrich Mine is currently owned by Paladin Energy Ltd with a 75% stake and CNNC Overseas Uranium Holding Ltd with a 25% stake. Paladin Energy sold the 25% to the Chinese National Nuclear Corporation (CNNC) in 2014 for a reported $190 million. The mine is under care and maintenance since 2018.
Tanzania is a land rich in minerals. Mining makes up more than 50% of the country's total exports, of which a large part comes from gold. The country has gold reserves of 10 million ounces, generating revenue of over a billion USD. Diamonds are also found in significant amounts. Since it was opened in 1940, the Williamson diamond mine has produced 19 million carats (3,800 kg) of diamonds. Gemstones, nickel, copper, uranium, kaolin, titanium, cobalt and platinum are also mined in Tanzania. Illegal mining and corruption are ongoing problems. In 2017, the government passed a series of bills aimed at increasing revenue from minerals after a scandal which caused the dismissal of the Minister for Energy and Minerals.
Uranium mining around Bancroft, Ontario, was conducted at four sites, beginning in the early 1950s and concluding by 1982. Bancroft was one of two major uranium-producing areas in Ontario, and one of seven in Canada, all located along the edge of the Canadian Shield. In the context of mining, the "Bancroft area" includes Haliburton, Hastings, and Renfrew counties, and all areas between Minden and Lake Clear. Activity in the mid-1950s was described by engineer A. S. Bayne in a 1977 report as the "greatest uranium prospecting rush in the world".
Kerr Addison Mines Ltd was a Toronto-based mining and gas company that owned various mines throughout Canada, including the Agnew Lake Mine, the Kerr-Addison Mine and Chesterville gold mine.
Uranium mining in the Elliot Lake area represents one of two major uranium-producing areas in Ontario, and one of seven in Canada.
