Abstract
Modeling allowed us to show Eh-pH parameters of the technogenic mineral formation in the mining-industrial technogenic system of polymetallic ores of Dal’negorsk district, to study the process of the hypergene mineral crystallization from solutions, to consider the qualitative and quantitative ionic composition of solutions, to show the role of hypergenesis in the contamination of surface and ground waters of the area. The aim of this work is to estimate the action of the CCM tailing oxidation on the hydrosphere of the district using the method of physicochemical modeling. The results obtained testify to a significant evacuation of a wide range of elements of sulfide ores (Zn, Pb, Cu, As, S) and enclosing rocks (Si, Al, Mg, Ca, K, Na) from the CCM tailing dumps into the surface waters polluting the hydrosphere with them.
