Hydromineral resources of salt lakes in western mongolia
Data on the study of composition and hydromineral resources of salt lakes in Western Mongolia are presented. Concentration U-238 in lake waters reaches 3 mg/l, Li - 100 mg/l, Br - 1 г/л, B - 100 mg/l. The largest salt lake of Western Mongolia (Hjargas lake) contains (tons): U-238 (6000), Li (20 000), Br (240000), B (240000). Proceeding from new data, uranium accumulation in water has been attributed to (i) location of the lakes and their watersheds in potential provinces of U-bearing rocks and (ii) uranium complexing with carbonate in presence of carbonate (bicarbonate) anions.
