Uranium mining (open cut and underground) .

    01.01.2016 · Low-grade uranium occurs with gold in the Witwatersrand area of South Africa. Large historic tailings piles from over 100 years of gold mining occur in the area. During the 1970–1990 period, as well as plants extracting uranium as a byproduct of direct gold mining and treatment, three significant tailings retreatment operations in the East Rand, Klerksdorp, and Welkom areas were established ...

    How Uranium Mining Works | HowStuffWorks

    Like other metals, uranium occurs naturally in rocks on the Earth's surface and can be extracted through uranium mining. Miners originally discovered uranium alongside radium, another element that was used as glowing, decorative paint (at least until people realized its harmful, radioactive effects). Uranium hit the market as a decorative glaze before its nuclear properties were discovered ...

    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 chemically ...

    Underground uranium mining is in principle no different from any other hard rock mining and other ores are often mined in association (e.g., copper, gold, silver). The uranium ore is extracted through mechanical means such as blasting, drilling, pneumatic drilling, picks and shovels, and then transported to the surface. Underground mining is usually used when the uranium is too far below the ...
