Abstract—Four types of high-purity quartzites from the Oka–Urik block, stock quartzites of the East Sayan Urengenur block, and granular quartz of the Patom plateau (vein 2821) are investigated. The textural and structural features and mineral and fluid inclusions (FIs) are determined for all types of raw quartz material. Schemes for producing high-purity quartz concentrates are developed for each type. Optical glass samples are produced by the vacuum-compression fusion and their spectral characteristics are measured.
