As can be seen from the table, a number of deposits of quartz sand
in the Republic more fully meet the requirements GOST 22551-77:
Quartz sand, ground sandstones, quartzite and veined quartz
for the glass
industry. Also, we are working to improve the quality of quartz raw
materials for the production of container glass [11] and
a number of
research works to develop an innovative technology for obtaining glass
products from local quartz sands.
Other components for glass production are calcium and magnesium-
containing oxides, the main raw materials of which are limestone and
dolomite, as well as industrial waste. The
developed and developed
dolomite quarries of Uzbekistan are located mainly in the Kashkadarya
region in the Dekhkanabad district. There is also information about the
reserves of dolomite in the Navoi and Bukhara regions. Limestone in
Uzbekistan is a common raw material, the
reserves of which are not
limited. The most chemically pure limestones are the Jizzakh and
Karatau deposits. The following table shows the
chemical compositions
of some dolomite deposits in Uzbekistan.
