Uraninite, also known as pitchblende, is a radioactive, uranium-rich mineral and ore with a chemical composition that is largely UO 2 but because of oxidation typically contains variable proportions of U 3 O 8. Radioactive decay of the uranium causes the mineral to contain oxides of lead and trace amounts of helium.
Metasomatite deposits consist of disseminated uranium minerals within structurally deformed rocks that have been affected by intense sodium metasomatism. [10] [11] Ore minerals are uraninite and brannerite. Th/U ratio in the ores is mostly less than 0.1. Metasomatites are typically small in size and generally contain less than 1000 t U 3 O 8. [11]
Tyuyamunite (pronounced tuh-YOO-ya-moon-ite) is a very rare uranium mineral with formula Ca(UO 2) 2 V 2 O 8 ·(5–8)H 2 O. It is a member of the carnotite group. It is a bright, canary-yellow color because of its high uranium content. Also, because of tyuyamunite's high uranium content, it is radioactive. [6]
This is a list of minerals which have Wikipedia articles. ... Pitchblende (a massive impure form of uraninite) Plessite (mixture of kamacite and taenite)
As of 2007, before the post-Fukushima price crash, there was an increase in price and demand for nuclear reactor fuel, making the Arizona Strip the site of high uranium mineral exploration. More than 500 breccia pipe targets in the Arizona Strip area were actively being explored by at least 11 mineral exploration companies. (May 25, 2007)
[12] [22] Uranium is found in hundreds of minerals, including uraninite (the most common uranium ore), carnotite, autunite, uranophane, torbernite, and coffinite. [12] Significant concentrations of uranium occur in some substances such as phosphate rock deposits, and minerals such as lignite , and monazite sands in uranium-rich ores [ 12 ] (it ...
Bowen also predicts that other natural options may become more popular, including minerals such as calcium carbonate (white) and iron oxides (red, brown and black), fruit and vegetable extracts ...
Minerals in unoxidized sandstone are uraninite and coffinite; minerals in oxidized zones include carnotite and tyuyamunite. [59] An airborne gamma radiation survey flown by the US Atomic Energy Commission in 1954 discovered high radiation readings over the Cave Hills area in Harding County, in the northwest corner of the state.
