Abstract
The author studied different technogenic massifs of various geneses containing sulphide sulphur and the research results have shown that under the influence of natural and man-caused factors mineral waste is subjected to weathering processes and transformation into new crystalchemical phases, which facilitates dispersion of toxic elements and their migration with ground waters. Studies help to establish that acid rock drainage formation and migration of pollutants is determined by physical and chemical metamorphization processes in infiltration waters. Ecological hazards from sulphide-bearing rock massifs are most adequately estimated with application of the acid indexing express-method.
