In this paper we have studied the possibility of determining the forms of uranium ions and minerals dissolved in water by using the Pourbaix diagram. Uranium in water with low uranium content exists in the form of uraninite or uranium dioxide UO2+ and with higher uranium content in the form of ions UO 2 (CO 3 ). By selecting carbonate minerals and calculating the saturation index, it is shown that uranium in the water of Eastern region of Mongolia dissolved in the forms of minerals such as quartzite CaMgUO 2 (CO 3 ) 3 (H 2 O) 12 , andersonite (Na 2 CaUO 2 (CO 3 ) 3 (H 2 O) 6 ), bayleyite (Mg 2 UO 2 (CO 3 ) 3 (H 2 O) 18 ), liebigite (Ca 2 UO 2 (CO 3 ) 3 (H 2 O) 10 ).
