Abstract: There are three major groups of the Ural quartz deposits: the Circumpolar group, the
Middle Ural group and the South Ural one. The Circumpolar group is represented by the
typical hydrothermal veined deposits. One of the big Circumpolar quartz deposit is
“Jelannoie” one. It is located in the monomineralic quartzy sandstone. The quartz vein
may be to 100 meters thick. Rutile, turmaline, zircon and sericite are the major accessory
minerals. The chief deleterious constituent in quartz is water, which is located in the gasliquid
inclusions. The effective method for H2O elimination is described. High quality
quartz glass may be produced after primary quartz enriching.
The Middle Ural is represented by giant quartz body “Mounain Chrustalnaia” .
Quartz body has a size 380X140X160 m. The content of quartz is 98.89%. Quartz deposit
was formed on the big massive of quartz-diorite and granite contact. The main accessory
minerals are microcline, muscovite, kaolin, hydrogoethite and pyrite. Quartz has a giant
crystalline structure. There is a specific enriching technology for this quartz deposit.
The South Ural group of quartz deposits is represented by a large body quartz vein,
disposed in East part of the Ufaleisky gneiss-migmatite complex. The length of quartz
vein area is 50 km. There are more than 3000 quartz veins on this area. Granulated quartz
is prevalent for this group of deposits. Field spars, micas, rutile, sphene, ilmenite and
carbonates are the main accessory minerals. Concentration of impurities in granulated
quartz is as the IOTA STD. There is standard technology of quartz enriching for these
