Open Pit Mining - an overview | ScienceDirect Topics

Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at
