Features of the Extraction of Rare Earth Elements from Igneous and Sedimentary Phosphate Ores

Using the dependences C(REE) = f(τ), fundamental differences in extraction of rare earth elements (REEs) from phosphate raw materials of sedimentary and igneous origin were identified, which consist in the extremal and monotonic plateauing behavior of the kinetic curves, respectively. The discovered features of nitric acid extraction of rare earth elements will make it possible to evaluate the prospects for integrated processing of raw materials and optimal conditions for their recovery from multicomponent systems.
