Other Identifiers: CRM 7-A The name monazite comes from a Greek word, monazein, which means "to be alone". It is an apt name as it is an allusion to the typical crystal habit of primary origin for monazite as isolated individual crystals in phosphatic pegmatites. Solitary c 2021-03-12 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 All commercially useful deposits consist of transported monazite sands liberated by erosion and concentrated by the action of water, which has sluiced away lighter materials and concentrated the heavy (D = 5.0 to 5.2) grains of monazite, together with ilmenite, zircon, garnet, and other dense minerals.

2 REPO 4 s + 3 H 2 SO 4 → R E 2 SO 4 3 s + 2 H 3 P O 4 However, decomposing monazite with alkali or acid wastes a large amount of water and raw materials. To remedy these problems, mechanical ball-milling method emerged in recent years. Monazite sand deposits are inevitably of the monazite- (Ce) composition. Typically, the lanthanides in such monazites contain about 45–48% cerium, about 24% lanthanum, about 17% neodymium, about 5% praseodymium, and minor quantities of samarium, gadolinium, and yttrium. Europium concentrations tend to be low, about 0.05%. Monazite is an important mineral resource, it is one of two minerals that are mined for their rare earth content, the other being bastnäsite which is even more important as a source of lanthanides but not as common in sand.
