Uranium Recovery Background The production of fuel for nuclear power plants starts with taking uranium ore from the ground and then purifying and processing it through a series of steps. Uranium recovery focuses on extracting natural uranium ore from the earth and concentrating (or milling) that ore. These recovery operations produce a product,

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 and the uranium …
