Open Pit Mining Methods

8231 open pit mining open pit mining refers to mining directly on the ground surface thereby producing an open pit this method is practical and costeffective when the uranium ore is located near the surface eg within 100 m underground mining and isl methods may be considered for sites that have uranium ores at deeper depths.
