The monazite is brownish red, yellow or green with greasy luster or glass luster. It is crisp, with hardness of 5 to 5.5 and density of 4.9 to 5.5g/cm3,and it is radioactive because it generally contains uranium, thorium and radium.

The monazite is a main rare earth mineral. In it，light rare earth (cerium group) oxides account for 39 to 74% and heavy rare earth (yttrium group)oxides account for 0 to 5%. It is used for extracting rare earth elements (metal, alloy and compounds) which are widely applied to fields of ferrous metallurgy and nonferrous metallurgy, production of glass and ceramics, electronics, electric lighting, television and laser technology, chemicalengineering industry, medical treatment and agricultural production.
