It is well known that zircon minerals contain significant levels of natural radioisotopes (500/1000 Bq/kg for 232Th and 1000/5000 Bq/kg for 238U). For this reason, the industrial processes of these minerals require specific impact analysis of the health effects and potential risk for people living near by the plant.

The mineral zircon (zirconium silicate) occurs in nature and is a coproduct of the mining and processing of heavy-mineral sands for the titanium minerals ilmenite and rutile. There are only a couple of domestic producers of zircon. Zirconia (zirconia dioxide) is produced directly from zircon by plasma fusion or electric-arc.

An ultra-rare mineral named reidite has been found in what is possibly the world's largest crater at Shark Bay in Western Australia. The crater is only the sixth-known on Earth to hold the mineral, which starts as common zircon before transforming to reidite under the pressure of space rocks slamming into the Earth's crust.
