Abstract
The research results are presented for dressability of quartzites from the Garga quartzite region of the East Sayan. From the detailed analysis of the structure, texture, mineral and fluid inclusions in the chemical constitution, bright veined quartzites and coaly veined quartzites were distinguished in the Urda-Gargan block. Both kinds are readily dressed up quartz concentrates of deep concentration. The fist quartzite kind can be used in manufacturing of transparent optical quartz glass, whereas the second variety is a promising feedstock for carbothermal production of silicon.
