Properties of monazite ore

Monazite is one of the main minerals in rare earth metal mines. Monazite is brittle, brownish red, yellow, sometimes brownish yellow, with an oily luster, complete cleavage, Mohs hardness of 5 to 5.5, and a density of 4.9 to 5.5 g/cm3. It is mainly produced as an accessory mineral in granite, syenite, gneiss, and granite pegmatite and is also made in hydrothermal deposits related to granite. It emits bright green fluorescence under ultraviolet light. Because it often contains uranium, thorium and radium, it is radioactive. Monazite is a common accessory mineral in intermediate-acid igneous rocks and metamorphic rocks, and also exists in some sedimentary rocks. Because monazite has relatively stable chemical properties and high density, it often forms coastal and alluvial placers. In addition, it can usually be enriched to form placers.

Application of Monazite

Monazite is a major rare earth mineral. Rare earth elements are widely used in ferrous and nonferrous metallurgy, glass and ceramic production, electronics, electrical lighting, television and laser technology, chemical industry, medical and agricultural production.
