  • Uranium - New World Encyclopedia

    Uranium ore is mined in several ways: by open pit, underground or by leaching uranium from low-grade ores (see uranium mining). Uranium ore typically contains 0.1 to 0.25 percent of actual uranium oxides so extensive measures must be employed to extract the metal from its ore. Uranium ore is crushed and rendered into a fine powder and …
