High Purity Quartz

Quartz is one of the most abundant minerals and occurs in many different geological settings. However, only very few deposits are suitable for high purity applications. Therefore, high purity quartz has become one of today’s key strategic minerals with applications in high-tech industries: semiconductors, high temperature lamp tubing, telecommunication and optics, microelectronics, and solar silicon applications.

Beneficiation of raw quartz into refined high purity products involves several steps which need to be adapted to minimize the specific impurities of the individual raw quartz feed in line with end-use applications. As a result, high purity quartz with impurity levels less than 20 ppm may be achieved so creating a valuable raw material which commands up to 5 EUR/kg.
