Nuclear reactor - Uranium mining and processing

2020-8-18  Nuclear reactor - Nuclear reactor - Uranium mining and 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
