The absence in Uzbekistan of facilities for the enrichment of quartz raw materials creates difficulties in raising product quality and competitiveness. The purpose of this work was to determine the possibility of enriching quartz raw materials by physical means. Sieving, washing, classifying, scrubbing, and magnetic influence have been used in the laboratory. For the glass industry, the most promising methods from the standpoint of enrichment of quartz sands as well as the possibilities of enrichment of vein quartz and quartzite are identified.
