For this purpose, solutions of GSK with

The research results of the mineralogical 
and chemical composition of salted sand 
Kazakhdarya showed that samples of sands 
Kazakhdarya are more mineralized. The 
predominant of the soluble salts are chlorides 
and sodium sulfate. SiO 2 content in the sand 
is 89.24% and the CaO, MgO, K

The results of research of influence of the
