  • Rare earth elements in sedimentary phosphate deposits

    Rare earth elements in sedimentary phosphate deposits: Solution to the global REE crisis? Our data suggest that phosphate rock currently mined in the United States has the potential to produce a significant proportion of the world's REE demand as a byproduct. Importantly, the size and concentration of HREEs in some unmined phosphorites
