HIGH PURITY ZIRCON SAND
Zirconia, ZrO2,has attracted considerable attention as a high technology material for industrial
applications because of its mechanical, thermal, electrical, chemical and optical properties. The
main mineral precursor of zirconia production is zircon (ZrSiO4). It is a natural combination of zirconium oxide (ZrO2) and silica (SiO2), which occurs as accessory mineral in silica rich igneous
rocks such as granite, pegmatite and nepheline syenite. It is also found concentrated with other
heavy minerals e.g., rutile, in river and beach sands.
