Innovative Processing Techniques for the Production of a Critical Raw Material the High Purity Quartz

Abstract

High purity quartz, is consider as a critical raw material and it is a rare commodity that only forms under geological conditions where a narrow set of chemical and physical parameters is fulfilled. When identified and following special beneficiation techniques, high purity quartz obtains very attractive prices and is applied in high technology sectors that currently are under rapid expansion such as photovoltaic solar cells, silicon metal – oxide wafers in the semiconductor industry and long distance optical fibers that are used in communication networks.
