As can be
seen from the table, quartz sand reserves are concentrated
in the Central Kyzylkum, where it is expedient to build an enrichment
complex for deironing quartz sand, which would give impetus to the
production of colorless sheet and container glass. There is little informa-
tion on the enrichment of quartz sands [3]. Some
deposits of quartz
sands of Uzbekistan were reported by us in the foreign press [4,5]. There
is a Kungrad soda plant producing soda ash (the plant's capacity is 200
thousand tons per year), and Kungrad sodium sulfate LLC produces
sodium sulfate in sufficient quantity and quality.
In addition, there are still many deposits of quartz sand, which are
not sufficiently studied and not developed. The lack of technology and
the necessary equipment for their enrichment
is considered a temporary
phenomenon.
Nevertheless, specialists from various institutes have established the
chemical composition of quartz sands in some deposits, which are
shown in Table 2 below.
