Uranium mining Energy Education
网页When uranium is found near the surface usually no more than 100 meters deep it can be extracted via open pit mining. In this method, soil and waste rock is removed by heavy equipment, allowing the ore to be accessed. The mines are carved out into sections called benches so that they can be mined methodically and safely. [4]
