Natural zircon sand ：ZRS-B primarily originates from coastal sand and is obtained through physical beneficiation processes such as water separation, electrostatic separation, and magnetic separation. Its theoretical composition is: ZrO2: 67.1%; SiO2: 32.9%. Due to impurities, zircon sand can appear in shades of purplish red, yellowish brown, pale yellow, pale red, green, gray, and colorless, with a diamond-like luster. Its Mohs hardness ranges from 7.5 to 8, and its specific gravity is between 4.4 and 4.8. It is brittle and exhibits a conchoidal fracture. Its refractive index is between 1.93 and 2.01, and its melting point is between 2340 and 2550℃. It is resistant to thermal shock, possesses good stability, and exhibits strong slag corrosion resistance. Primary processing of natural zircon sand concentrate can be applied in refractory and glass-ceramic industries; professional grinding produces zircon powder and zirconium silicate products for use in the ceramic industry; and advanced processing is used to produce high-purity zirconia and chemical zirconium products for use in precision ceramics, leather, and other industries.
