On influence of technogenic sewage on physical and chemical characteristics of the freshwater reservoir
The effect of industrial sewage on the physico-chemical characteristics of Lake Imandra has been estimated. The numerical modelling with the program complex Selector-C has shown that industrial sewage leads to increase of concentration of Na+, K+, Cl, F, SO4-2, SiO2, . The water is saturated with respect to Ca, Na, K, P, Al, Si. If the sewage volume is three times greater, the value of pH throughout the water body increases by 0.4.

Natural surface and underground water formation conditions in the Kola North (an example of the Khibiny Massif)
Processes of surface and underground water formation in the Khibiny massif have been studied using a physical-chemical model of the "water – rock – atmosphere – organic substance" system. The obtained model solutions are indicative of the fact that formation of surface and underground water of the Khibiny massif takes place on the whole in the framework of the considered system without attracting a hypothetical outside source. The results are of practical and methodological importance for assessment of prediction of the man-induced impact on water systems in conditions of Subarctic.

Geoecological validation of mechanisms and parameters of physical-chemical processes facilitating the in-depth processing of complex suphide ores and mining wastes
The advisability of processing copper-nickel ore dressing tailings of current production has been substantiated. The optimal parameters of metal leaching with sulphuric acid have been determined. In laboratory experiments the geotechnological extraction of non-ferrous metals from a leaching layer representing a tailing material of fraction +0.063 mm has been studied. When investigating the geotechnological processes of non-ferrous metal extraction on the basis of two copper-zinc ore deposits located in the Urals, the authors have come to the conclusion that heap leaching is of little use for the ores of the Letneye deposit. Leaching results for the Yaman-Kasy ore have shown more promise.
