Uranium mining in the United States produced 224,331 pounds (101.8 tonnes) of U 3 O 8 in 2023, 15% of the 2018 production of 1,447,945 pounds (656.8 tonnes) of U 3 O 8. The 2023 production represents 0.4% of the uranium fuel requirements of the US's nuclear power reactors for the year.
The highest grade uranium deposits are found in the Athabasca Basin in Canada, including the two largest high grade uranium deposits in the world, Cigar Lake with 217 million pounds (99,000 t) U 3 O 8 at an average grade of 18% and McArthur River with 324 million pounds (147,000 t) U 3 O 8 at an average grade of 17%. These deposits occur below ...
World uranium reserves in 2010. Uranium reserves are reserves of recoverable uranium, regardless of isotope, based on a set market price. The list given here is based on Uranium 2020: Resources, Production and Demand, a joint report by the OECD Nuclear Energy Agency and the International Atomic Energy Agency. [1] Figures are given in metric ...
The largest uranium producers are Cameco, Rio Tinto, Areva, KazAtomProm and ARMZ-TVEL. The production methods employed are conventional underground and open cast (50%) and in-situ leaching (50%). About 50 uranium production centers are operational.
[3] [7] [10] The uranium ore minerals include uraninite and coffinite. The age of the uranium formation is assumed to be the same as the caldera tuff, which is approximately 16.1 million years. [7] Other deposits in the caldera contain ores of antimony, cesium, and lithium [11] [12] (potentially, one of the biggest mines in the world). [13]
The Colorado Plateau holds major uranium deposits, and there was a uranium boom in the 1950s. The Atlas Uranium Mill near Moab has left a problematic tailings pile for cleanup. As of 2019 [update] , 10 million tons of tailings had been relocated out of an estimated 16 million tons. [ 9 ]
The site was discovered during uranium prospecting in the 1970s, inspired by the Ambrosia Lake deposit in Canada, with exploration led by the Marline Oil Corporation. Uranium is found within a structural trap, surrounded by biotite gneiss, with staining from hematite overlying the Fork Mountain schist. Hematite staining on the ground surface is ...
The McArthur River Uranium Mine, in northern Saskatchewan, Canada, is the world's largest high-grade uranium deposit. The mine is owned by Cameco (70%), and Orano Canada (30%) (formerly Areva Resources Canada , formerly COGEMA Resources Inc.) Cameco is the mine operator.
