Uranium is a widely distributed metal with large low-grade deposits that are not currently considered profitable. As of 2015, 646,900 tonnes of reserves are recoverable at US$40 per kilogram of uranium, while 7,641,600 tonnes of reserves are recoverable at $260 per kilogram. [ 2 ]
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 ...
Breccia uranium deposits are found in rocks that have been broken due to tectonic fracturing, or weathering. Breccia uranium deposits are most common in India, Australia and the United States. [20] A large mass of breccia is called a breccia pipe or chimney and is composed of the rock forming an irregular and almost cylinder-like shape.
Uranium is produced from the Somair mine at Arlit, 63.4% owned by Orano Cycle and 36.66% by Niger state mining assets company Société du patrimoine des mines du Niger, known as SOPAMIN, and has produced nearly 68,000 tonnes (149,900,000 pounds) of uranium since operations began in 1971; and the Akouta mine at Akokan, owned by Orano Cycle (34% ...
Australia has 28% of the world's known uranium ore reserves [83] and the world's largest single uranium deposit is located at the Olympic Dam Mine in South Australia. [85] There is a significant reserve of uranium in Bakouma, a sub-prefecture in the prefecture of Mbomou in the Central African Republic. [86]
It is best known as the world's leading source of high-grade uranium and currently supplies about 20% of the world's uranium. [1] The basin is located just to the south of Lake Athabasca, west of Wollaston Lake, and encloses almost all of Cree Lake. It covers about 100,000 square kilometres (39,000 sq mi) in Saskatchewan and a small portion of ...
About 201 million tonnes were located at decommissioned uranium mining sites and about 17 million tonnes were located at active sites. The inventory or uranium tailings were held as follows: 99.4 million tonnes (46%) Rio Algom; 69.6 million tonnes (32%) Denison Mines; 30.9 million tonnes (14%) Cameco; 5.2 million tonnes (2%) Orano Canada
