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 Wyoming uranium mining industry was hard-hit in the 1980s by the drop in the price of uranium. The uranium-mining boom town of Jeffrey City lost 95% of its population in three years. By 2020, the only active uranium mine in Wyoming was the Smith Ranch-Highland in-situ leaching operation in the Powder River Basin, owned by Cameco. [107]
Mining stopped in the Monument Valley district in 1969, after producing 8.7 million pounds (3900 metric tons) of uranium oxide, more than has been produced from any other uranium mining district in Arizona. [3] In 2005 the Navajo Nation declared a moratorium on uranium mining on the reservation, for environmental and health reasons.
The US government remained, by law, the sole purchaser of uranium in the United States until 1971, but private companies operated the mines" (Brugge and Goble, "The History of Uranium Mining and the Navajo People"). [1] Widespread uranium mining began on Navajo and Lakota lands in a nuclear arms race with the Soviet Union throughout the Cold War.
Uranium mining in New Mexico was a significant industry from the early 1950s until the early 1980s. Although New Mexico has the second largest identified uranium ore reserves of any state in the United States (after Wyoming ), no uranium ore has been mined in New Mexico since 1998.
Uranium ore (pitchblende in dolomite) from the vein-type deposit Niederschlema-Alberoda Polymetallic uranium ore, Marienberg, Erzgebirge Mountains, Germany. Vein deposits play a special role in the history of uranium: the term "pitchblende" ("pechblende") originates from German vein deposits when they were mined for silver in the 16th century.
Stanleigh Mine is located 2 miles northeast of Elliot Lake and was first staked by H. S. Strouth, the chief of mining of Standard Ore and Alloys Corporation, later Stanleigh Uranium Mining Corporation. Ownership was subsequently transferred to Miliken Lake Uranium Mines and Northspan Uranium Mines Limited (who owned Lacnor Mine). [4]
The Czech Republic is the birthplace of industrial-scale uranium mining. Uranium mining at Jáchymov (at that time named Joachimsthal and belonging to Austria-Hungary) started in the 1890s on an industrial scale, after the silver and cobalt production of the deposit declined. Uranium was first utilised to produce mainly yellow colours for glass ...
