Recovery of rare earth elements from phosphate rock

2018-3-1  Phosphate rock, formulated as Ca 5 (PO 4) 3 (F, OH, Cl), are classified as igneous apatite and sedimentary phosphorite according to their mineralization mechanism . In phosphate rock, REEs present majorly in the form of isomorphous substitution for Ca and deposit as the REE-francolite that can be easily released into leaching solution by mineral acids.
