Description
Summary:The paper describes the physicochemical modeling of slime water formation in the dried tailing dumps of the Central and Krasnorechensk concentrating mills in the positive temperature range. The Eh and pH parameters of the equilibrium solutions, quantitative element compositions of the latter, and the compositions of the crystallizing hypergene and technogenic minerals were determined. The modeling was carried out on the basis of the averaged chemical compositions of the tailings. The resulting data point to a possible hydrosphere pollution with slime waters containing elements of sulfide ores and enclosing rocks, which may occur over the entire considered temperature range, both before hypergene mineral deposition and after that.
