There are several themes of uranium ore deposit formation, which are caused by geological and chemical features of rocks and the element uranium. The basic themes of uranium ore genesis are host mineralogy, reduction-oxidation potential, and porosity. Uranium is a highly soluble and radioactive heavy metal.
Uranium-235, the fissile isotope of uranium used in nuclear reactors, makes up about 0.7% of uranium from ore. It is the only naturally occurring isotope capable of directly generating nuclear power. While uranium-235 can be "bred" from 234
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 ...
A small amount of uranium ore was mined in the mid-1950s from a surface exposure at Cement in Caddo County. The uranium occurred as carnotite and tyuyamunite in fracture fillings in the Rush Springs Sandstone over the Cement anticline, where the sandstone is bleached.
Uranium is more plentiful than antimony, tin, cadmium, mercury, or silver, and it is about as abundant as arsenic or molybdenum. [12] [22] Uranium is found in hundreds of minerals, including uraninite (the most common uranium ore), carnotite, autunite, uranophane, torbernite, and coffinite. [12]
In December, the U.S. Department of Energy awarded contracts worth more than $6 billion to a series of companies in the business of enriching uranium ore for use as nuclear fuel -- fuel that could ...
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.
The ore consisted of the uranium-vanadium minerals tyuyamunite, metatyuyamunite, and carnotite, along with the copper minerals covellite, chalcocite, azurite, and malachite, and the copper-vanadium mineral volborthite, in the Maroon Formation of Pennsylvanian-Permian age. The ore is associated with faulting-induced fractures in the sandstone. [21]
