High-purity quartz sand is the key raw material of photovoltaic,semiconductor and other high-tech industries.In view of the problem of removing Fe,Al,Ti and other impurities in natural quartz sand,this paper systematically analyzes the basic principles and processes of many high purity quartz sand processing technologies,such as physical,chemical and ther-mal processing.Combined with the actual case of a material company,a set of effective technical scheme of high purity quartz sand is put forward.The practice shows that the scheme is feasible and economical,and the purity of high purity quartz sand products is stable to more than 99.999%,which can meet the needs of high-end applications.
