Mining & Milling - Cameco U101

In some circumstances, ore may be mined by in situ recovery, a process that dissolves the uranium while still underground and then pumps a uranium-bearing solution to the surface. Open pit mining When uranium ore is found near the surface, generally less than 100 metres deep, it is typically extracted by open pit mining.

Underground Uranium Mining - Oresome Resources

Underground mining is the method of mining used when the ore being sought is well below the Earth’s surface. An alternative to underground mining is open-cut mining, which is possible when the ore is close to the surface. All mines require ventilation and uranium mines are particularly well-ventilated to ensure exposure to radiation is minimised.
