Extraction and Separation of Rare Earth Elements From Their Concentrate with Apatite Base

Extraction and separation of rare earth elements from their concentrate with apatite base. Concentrate of rare earth elements with apatite concentrate base contains 30% of LREE,HREE and MREE that have gained the knowledge of its technology. Also, we have even reached the separation of Cerium, Lanthanum and Neodymium.
The Challenge: Isolation and extraction of other rare earth elements in concentrate by a method applicable in semi-industrial and industrial scale.
