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.

Uranium Ore. With the decreased market price of uranium beginning in the 1980s, U.S. producers turned increasingly to in-situ recovery (ISR) operations to extract uranium from ore. In-situ recovery (also known as "solution mining") is when fluids are injected into an ore-bearing aquifer to mobilize uranium, which becomes soluble in water.
