Material and Energy Requirement for Rare Earth Production

The energy input for processing 1 tonne of REMs varies depending on its concentration in the primary ore mined. At Mountain Pass, the ore mined contains an average of 7.7% of REO and the recovery rate is about 90% due to a very fine grinding of the minerals.21 Thus, 17 tonnes of mineral ores and an energy input of 1.74 GJ are …

Open Pit Mining

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 deeper depths.
