    • Monazite

      Monazite can be isolated as a nearly pure concentrate by the use of gravity, magnetic, and electrostatic separation. Monazite sand deposits are inevitably of the monazite ( Ce ) composition. Typically, the lanthanides in such monazites contain about 4548% cerium , about 24% lanthanum , about 17% neodymium , about 5% praseodymium , and minor quantities of samarium , gadolinium ,
