EXTRACTION OF RARE EARTHS FROM MONAZITE SAND RARE EARTH RESIDUES. Introductory. More than three thousand tons of monazite sand are decomposed annually in order to obtain the thorium necessary for the manufacture of incandescent gas mantles. Since monazite is primarily a phosphate of the cerium group metals of the rare earths and as the
Processing of monazite sands Abstract For the past ten years, much effort has been expended by several research teams to develop an economic process for recovering thorium, rare earths and uranium from monazite sands. Recently, a process was developed at the Ames Laboratory which possessed many attractive features.

Dissolution of the solid reaction products in water and clarification of the solution by allow ing the acid-insoluble sludge to settle, 3. Fractional precipitation of thorium phosphate by Monazite sand is found in large amounts in India and Brazil, and Australia has large deposits as well.
In some of Brazil's HBNRAs, monazite sand deposits are abundant on certain black sand beaches. The external radiation levels on these black sand beaches reach as high as 50 μGy h −1 . The minerals that are present in abundance in these coastal regions of Brazil are monazite, rutile, ilmenite, zircon, cassiterite, thorianite, pyrochlore and niobate-tantalite. Monazite sand: Monazite sand with a resinous luster from Malaysia. Monazite is produced from heavy-mineral concentrates and then separated out by specific gravity, magnetic processes, and other processes.
