Abstract
The results of physicochemical modeling of oxidation of sulfide minerals in the Central Concentrating Mill tailing dump (Komsomolsky tin-ore district) with account taken of the cementation zone in the temperature range from-25 to +45°C are given. The Eh-pH parameters for the formation of micropore solutions in technogenic systems have been determined at different host rock-sulfide ratios (95: 5, 90: 10, 80: 20, 60: 40, 40: 60, 20: 80, 10: 90, 5: 95). Crystallization of hypergene minerals from the micropore solutions have been considered, their qualitaitve and quantitative ion compositions have been determined, and their effect on the hydrosphere has been assessed.
