Bischofite natural and chemical resources at the East European platform and its use in balneology

Comparison the bischofite of leaching brines of Volga and separate domes of Caspian Depression with Dnepro-Donetsk pools and Lakes Elton is carried out, the Dead Sea also is revealed that brines of leaching of Dnepro-Donetsk avlakogen with a mineralization of 446-461 g/dm3 possess the lowered mineralization in comparison with Volga region (to 511 g/dm3). Content of magnesium strongly doesn't change in the Volga region basin and makes 107,0-115,5 g/dm3, and in Dnepro-Donetsk - 108,2-114,3 g/dm3. Concentration of bromine in a bischofite brine of Dnepro-Donetsk avlakogen reaches 7619 mg/dm3, and in the Volga region basin - 5354 mg/dm3, what is much lower. Everywhere there is no iodine. Bischofite brines of Russia and Ukraine don't concede to resorts of the Dead Sea on balneological indicators, and on bromine and magnesium considerably exceed indicators of the Dead Sea.
