Radioactive Waste From Uranium Mining and …

Uranium is a naturally-occurring radioactive element that has been mined and used for its chemical properties for more than a thousand years. It is now primarily used as fuel for nuclear reactors that make electricity. Uranium can be recovered in two ways: by conventional mining of the rock (ore), or by using strong chemicals to dissolve uranium from the rock that is still in the ground and ...

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.

Uranium mining - Canadian Nuclear Association

When uranium ore is found near the surface, generally less than 100 metres deep, it is typically extracted by the open-pit mining method. Open-pit mining begins by removing soil and waste rock on top of the ore, to expose the hard rock. Then a pit is excavated to access the ore. The walls of the pit are mined in a series of benches to prevent them from collapsing. To mine each bench, holes are ...
