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. Soil and waste rock is removed using conventional earth moving processes to access the ore. The walls of the pit are mined in a series of benches to prevent them from collapsing.
