Rare Earth Mineral Deposits and Their Industrial

Abstract. Rare earth mineral deposits can be subdivided into endogenic, exogenic and metamorphic mineralizations. Today, industrially most important is bastnaesite from the primary deposit of Mountain Pass, California, and Bayan Obo, P.R. China, followed by monazite from the coastal sands of Australia, Brazil, India and Indonesia.
