Аннотация
Oxidation of tailings in the tailing dump of Vysokogorskoe deposit (Kavalerovsky district) in the temperature range from 0 to +45°C was simulated with successive exclusion of each of the sulfide minerals present therein (pyrite, pyrrhotite, galena, sphalerite, arsenopyrite, and chalcopyrite). The Eh-pH parameters for anthropogenic mineral formation were determined at different host rock–sulfide ratios (95: 5, 90: 10, 80: 20, 60: 40, 40: 60, 20: 80) in the tailings. Crystallization of supergene minerals was analyzed, qualitative and quantitative ionic compositions of solutions were determined, and their impact on the hydrosphere was assessed.
