Uranium Mining and Extraction from Ore - Robert B. Laughlin

Mar 21, 2012 · For underground mines, once the site has been identified, a mine shaft is typically drilled down to the ore bed. Since drilling is used in both of these processes, large amounts of water are employed to prevent airborne radiation exposure to laborers. These processes are very similar to bulk mining techniques employed for other materials.
