  • Uranium Mining Overview - World Nuclear Association

    Vast amounts of uranium also occur in the world's oceans, but in very low concentrations. The largest-producing uranium mines in 2021 Note 1: SMCC, a joint venture between Kazatomprom and Uranium One, reported combined production of 2321 tU in 2021 at its two mines, South Inkai 4 and Akdala.


  • Nuclear reactor - Uranium mining and processing | Britannica

    Uranium mining and processing Uranium is extracted from ores whose uranium content is often less than 0.1 percent (one part per thousand). Most ore deposits occur at or near the surface; whether they are mined through open-pit or underground techniques depends on the depth of the deposit and its slope.


  • How is uranium made into nuclear fuel?

    The mining of uranium Uranium is found in small amounts in most rocks, and even in seawater. Uranium mines operate in many countries, but more than 85% of uranium is produced in six countries: Kazakhstan, Canada, Australia, Namibia, Niger, and Russia. Historically, conventional mines (e.g. open pit or underground) were the main source of uranium.


  • Uranium: Where Is It? - New Mexico Bureau of Geology ...

    In intermediate to acidic igneous rocks and pegmatites, the uranium-rich minerals are direct precipitates (no dissolution and remobilization. Deposits of this type are found in USA, Namibia, Greenland, Canada and South Africa. Metasomatic deposits. Hydrothermal alteration of deformed basement rocks.


  • What is Uranium? How Does it Work - World Nuclear Association

    Uranium may also be mined by in situ leaching (ISL), where it is dissolved from a porous underground ore body in situ and pumped to the surface. The end product of the mining and milling stages, or of ISL, is uranium oxide concentrate (U 3 O 8 ). This is the form in which uranium is sold.


  • Domestic Uranium Production Report - Annual

    At the end of 2021, Shootaring Canyon Uranium Mill and White Mesa Mill in Utah and Sweetwater Uranium Project in Wyoming were on standby with a total capacity of 5,750 short tons of material per day. In Wyoming, one heap leach plant was in the planning stages (Sheep Mountain).


  • Uranium mining - Wikipedia

    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.


  • List of countries by uranium production - Wikipedia

    This contains lists of countries by uranium production. The first two lists are compiled by the World Nuclear Association, and measures uranium production by tonnes mined. The last list is compiled by TradeTech, a consulting company which specializes in the nuclear fuel market.


  • Uranium Mines and Mills Location Database | US EPA

    View the report. In the early 2000s, EPA created the Uranium Mines and Mills Location Database as part of its investigation into the potential environmental hazards of wastes from abandoned uranium mines in the western United States. The database is comprised of information regarding known or potential mine and mill locations and mine features ...


  • Where our uranium comes from - U.S. Energy Information ...

    There are economically recoverable uranium deposits in the western United States, Australia, Canada, Central Asia, Africa, and South America. Owners and operators of U.S. nuclear power reactors purchased the equivalent of about 46.74 million pounds of uranium in 2021. Sources and percentage shares of total U.S. purchases of uranium in 2021 were:


  • Uranium mining in the United States - Wikipedia

    Uranium was mined at the Stanley district in Custer County, Idaho from 1957 to 1962. Deposits occur as veins in granite of the Cretaceous Idaho Batholith, and in strataform deposits in possibly Paleocene arkosic conglomerates and sandstones between the underlying Idaho Batholith and overlying Challis Volcanic Group ( Eocene ).


  • The nuclear fuel cycle - U.S. Energy Information ...

    Uranium milling After the uranium ore is extracted from an open pit or underground mine, it is refined into uranium concentrate at a uranium mill. The ore is crushed, pulverized, and ground into a fine powder. Chemicals are added to the fine powder, which causes a reaction that separates the uranium from the other minerals.


  • The 10 Biggest Uranium Reserves In The World - WorldAtlas

    Uranium exploration began in the country in 1943. Currently, Kazakhstan has about 50 deposits in 6 provinces. 2. Canada Canada was the world's largest uranium producer for many years, accounting for 22% of world output at the time, but in 2009 was overtaken by Kazakhstan.


  • Where Does Uranium Come From? - Nuclear Energy Institute

    Ore mined from open-pit and underground mines travels to a conventional mill. Solvents or ion exchange processing removes the uranium, resulting in uranium oxide, or yellowcake, which is then filtered, dried and packaged. Uranium can also be recovered through a process known as in situ recovery (ISR) mining where oxygenated groundwater is ...


  • Uranium Mines and Mills Location Database | US EPA

    The Uranium Mines and Mills Location Database is designed for use with geographic information system (GIS) software. A geographic projection of the uranium locations found in the database may be generated with GIS software, using the files available in the ZIP file below.


  • Nuclear Fuel Facts: Uranium | Department of Energy

    Uranium occurs naturally in low concentrations in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. Uranium ore can be mined from open pits or underground excavations. The ore can then be crushed and treated at a mill to separate the valuable uranium from the ore.


  • Uranium mining by country - Wikipedia

    Uranium was mined from 1947 to 1990 from mines in Saxony and Thuringia by the SDAG Wismut. It was mostly used by the Soviet Union to build nuclear fission weapons, also as fuel for nuclear power plants. In West Germany more limited mining took place at Ellweiler, Rheinland-Pfalz (1959–1964), and Menzenschwand, Baden-Württemberg (1961–1991). [29]


  • World Uranium Mining - World Nuclear Association

    About two-thirds of the world's production of uranium from mines is from Kazakhstan, Canada and Australia. An increasing amount of uranium, now over 60%, is produced by in situ leaching. In 2021 Kazakhstan produced the largest share of uranium from mines (45% of world supply), followed by Namibia (12%) and Canada (10%).


  • Uranium Enrichment | NRC.gov

    When uranium is mined, it consists of approximately 99.3% uranium-238 (U 238 ), 0.7% uranium-235 (U 235 ), and < 0.01% uranium-234 (U 234 ). These are the different uranium isotopes. Isotopes of uranium contain 92 protons in the atom's center or nucleus. (The number of protons in the nucleus is what makes the atoms "uranium.")
