Zircon is a zirconium silicate mineral. It is the principle source of the element zirconium (Zr) 1  usually small and inclusion-rich.  Zircon is highly resistant to weathering (maybe the most resistant of any mineral) This, and its high specific gravity, favor its concentration in placer deposits and alluvial gem gravels.
Zirconium Chemicals. There is a wide range of zirconium chemicals, used either for their intrinsic properties in diverse applications, or as intermediates for manufacture of other derivatives of zirconium.The principal precursor or building block for zirconium chemicals is zirconium oxychloride, known as ZOC.ZOC is produced from zircon sand by a variety of processes, generally involving caustic fusion, dissolution in hydrochloric acid and separation.he principal precursor or building block for zirconium chemicals is zirconium oxychloride, known as ZOC.
