Uranium ore - Wikipedia

Uranium ore deposits are economically recoverable concentrations of uranium within the Earth's crust.Uranium is one of the more common elements in the Earth's crust, being 40 times more common than silver and 500 times more common than gold. It can be found almost everywhere in rock, soil, rivers, and oceans. The challenge for commercial uranium

Uranium processing | Britannica

Uranium processing, preparation of the ore for use in various products.. Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements, so that it is not valued for structural applications.

Uranium-238 Decay Chain - Atari Dog Daze

When uranium is extracted chemically from its ore, it is separated from its decay products. How much of each decay product is produced by pure uranium after it's extracted? For the time being, let's ignore the small amount of uranium-234 and uranium-235 in the rock, and assume that all the uranium freshly extracted from its ore is pure uranium-238.

Uranium Enrichment | NRC.gov

The gaseous diffusion process uses molecular diffusion to separate a gas from a two-gas mixture. The isotopic separation is accomplished by diffusing uranium [which has been combined with fluorine to form uranium hexafluoride (UF 6) gas] through a porous membrane (barrier), and using the different molecular velocities of the two isotopes to achieve separation.

Water injected with oxygen (or an alkali, acid or other oxidizing solution) is circulated through the uranium ore, extracting the uranium. The uranium solution is then pumped to the surface. The uranium solution from the mines is then separated, filtered and dried to produce uranium oxide concentrate, often referred to as ‘yellowcake’.

Uranium Radiation Properties

Chemical separation of uranium (e.g. in a uranium mill) removes the decay products, while the isotopic composition of the uranium remains unchanged. However, within a few months, the short-lived decay products Th-234, Pa-234m, and Th-231 grow in, again. So, in most practical situations, their presence has to be taken into account, as well.

Separation of thorium from uranium ore | SpringerLink

Thorium-230 has many research applications, but there is not a commercial source of this isotope. However, since 230Th is part of the 238U decay chain, it can be separated from naturally occurring uranium. In this work, a novel procedure was developed to separate thorium from uranium ore, consisting of leaching, liquid–liquid extraction, precipitations and ion exchange chromatography.

Oct 26, 2006 · When you finish processing uranium ore, what you have is uranium oxide. Uranium oxide contains two types (or isotopes) of uranium: U-235 and U-238. U-235 is what you need if you want to make a bomb or fuel a nuclear power plant. But the uranium oxide from the mine is about 99 percent U-238. So you need to somehow separate the U-235 from the U ...

Natural uranium contains 0.7% of the U-235 isotope. The remaining 99.3% is mostly the U-238 isotope which does not contribute directly to the fission process (though it does so indirectly by the formation of fissile isotopes of plutonium). Isotope separation is a physical process to concentrate (‘enrich’) one isotope relative to others.
