Geology Word of the Week: U is for Uraninite

 · Botryoidal uraninite. Image taken from wikipedia commons here. def. Uraninite:A uranium-rich mineral with the formula UO2 (uranium oxide). Often, part of the uraninite is oxidized with the formula UO3. Uraninite is the primary ore for uranium and can also be mined for other elements such as radium, thorium, and lead, which are decay products of radioactive uranium. Uraninite deposits are.

Uranium Mining and Extraction from Ore

Uraninite has an ideal chemical composition of UO 2, but the mineralogical and chemical composition of specimens varies in response to their levels of oxidation and radioactive decay. "Pitchblende" is an archaic name that was used for uraninite and other.

Uranium enrichment

Uranium enrichment is a process that is necessary to create an effective nuclear fuel out of mined uranium by increasing the percentage of uranium-235 which undergoes fission with thermal neutrons.Although many reactors require enriched uranium fuel, the Canadian-designed CANDU, the British Magnox reactor and the proposed Molten salt reactor can use natural uranium as their fuel.

Uranium mining

A hydrometallurgical process is used to produce uranium from uranium ore, using chemicals and solutions to extract the uranium from the ore matrix. The process is complete when the final uranium product, known as yellowcake, is produced in a sufficient high purity (typically 75 to 85 percent U 3 O 8 ) so that it can be used in the remainder of the nuclear fuel production cycle.

Uranium — How Is It Mined?

Underground mining is used to get at higher concentrations of uranium that are too deep to get at from open-pit. The ore is drilled, then blasted to create debris which is then transported to the surface, then on to a mill. An example of a uranium mine.
