Results are presented for comprehensive study of the substance composition of quartzites with the aim of de
termining the content of micro- and macroimpurity components. Impurity distribution is studied for the first
time in the main rock-forming, accessory and secondary minerals of conditioned raw material. Information is
provided about the complete chemical composition, necessary for expanding the assortment of production
from siliceous raw material.
The state balance at 01.01.2001 in Russia was considered
(with calculation of reserves) to be 30 deposits of quartzites
and quartz sandstones suitable for use in industry mainly as
flux raw material in nonferrous metallurgy and a silica com-
ponent for melting a series of ferroalloys (ferrosilicide, etc.).
The highest purity of quartz rock varieties is raw material for
producing dinas, and also for preparing crystalline silicon
and silicon carbide. Currently and in the near future the re-
serve deposit of the Karaul Mountain quartzites is a unique
raw material base with respect to purity for producing silica
refractories and quartz fluxes in our country. Large scale
mining and processing of quartzites of this deposit has been
carried out for 70 years by OAO Pervoural Dinas Plant.
An important criterion of quality and grade for quartzite
raw material is its chemical composition (Table 1) and the re
quirement for different users is strictly individual both with
respect to the content of macroimpurities (0.1 – 1.0%) and
also for the amount of microcomponents (0.01 – 0.1%). Si
multaneously the chemical composition, present in oxide or
elemental form, relates to the number of main geochemical
characteristics of natural mineral formation: minerals, rocks,
deposits and geochemical formations. In the group of applied
geochemical criteria there are also qualitative and quantita
tive data for the distribution of economic chemical elements
and harmful impurities in minerals, a change in their concent
ration in a deposit (in plan and in cross section) in relation to
lithological, tectonic, geomorphological and other natural
and technogenic factors.
Brief information about the substance composition of
quartzites and enclosing rocks of the Karaul Mountain de-
posit are provided in a series of publications [1 – 4], although
there is no information about complete chemical composi-
tion of raw material, distribution of impurities in rock form-
ing and accessory (secondary) minerals, and as a whole for
individual area (beds) of the deposit.
