- Abstract:
- This article presents theoretical studies of the physicochemical mechanisms of leaching processes related to the oxidation-reduction conditions of the environment, the ability of elements to form compounds with other elements, form ions of varying valence, yield soluble or gaseous compounds. The Semizbay deposit's ores are visually indistinguishable from the host rocks and are distinguished only by sampling. Uranium is found in these ores in both mineral and sorbed forms. The ores are primarily loose and poorly cemented; carbonate ores make up 20% of the deposit's ores and are the primary acid absorbers during sulfuric acid leaching. The ionic composition of the uranium leaching solution during the acidification stage of the formations was analyzed, and the interaction of sulfuric acid solutions with the ore-hosting rocks was assessed.
