Fact Sheet on Uranium Enrichment Background The fuel of a nuclear power plant is uranium, but only a certain type of uranium atom can be easily split to produce energy. This type of uranium atom –– called uranium-235 (U235) –– comprises less than one percent by weight of the uranium as it is mined or milled. To make
— Uranium processing - Leaching, Extraction, Purification: Roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions. For the successful operation of all leaching systems, uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process. …
History. On 23 Aug 2007 The Cabinet Committee on Economic Affairs (CCEA) of Government of India cleared the setting up of a uranium mine and processing plant by the Uranium Corporation of India with an estimated cost of ₹ 11.06 billion (US$140 million). [7] After that the Uranium Corporation of India acquired 1,122 acres (454 ha) of government …
Key Facts. Before its use in a nuclear reactor, a series of processing steps converts mined uranium ore into ceramic pellets, which are loaded into fuel rods.; Ore mined from open-pit and underground mines travels to a conventional mill. Solvents or ion exchange processing removes the uranium, resulting in uranium oxide, or yellowcake, which is then filtered, …

Nuclear reactor - Uranium Mining, Processing: Uranium is extracted from ores whose uranium content is often less than 0.1 percent (one part per thousand). Most ore deposits occur at or near the surface; whether they are mined through open-pit or underground techniques depends on the depth of the deposit and its slope. The mined ore is crushed …

— When uranium is mined, it consists of approximately 99.3% uranium-238 (U 238), 0.7% uranium-235 (U 235), and < 0.01% uranium-234 (U 234). These are the different uranium isotopes. Isotopes of uranium contain 92 protons in the atom's center or nucleus. (The number of protons in the nucleus is what makes the atoms "uranium.")
