The Mountain Pass Rare Earth Mine is an openpit mine of rareearth elements on the south flank of the Clark Mountain Range, just north of the unincorporated community of Mountain Pass, California, United States.The mine once supplied most of the world''s rareearth elements. Owned by MP Materials, it is the only rare earth mining and processing facility in the United States.
The main components were iron and silica. The concentrations of rare earth elements were analyzed by LA–ICP–MS. Results in Table 2 show that the cerium concentration was 2.5 × 10 3 mg/dm 3, which was the highest of the rare earth elements.
