Abstract
The main objects of the research were the deposits of noble and non-ferrous metals of the Urals, Siberia and Novaya Zemlya. It is shown that the establishment of a pomineral balance of distribution of chemical elements in ores, the study of variability of the material composition and stereometric features of ores in the geological space is extremely important to solve the problems of rational use of ore deposits and the prediction of environmental consequences of their development. When assessing the environmental impact of the deposits involved in the exploration and exploitation, both the regularities of distribution of toxic elements and minerals in the volumes of ore bodies and fields, and landscape-geochemical conditions determining the factors of migration and accumulation of these components after their extraction on the earth surface should be taken into account. For geological-economic and environmental forecasting it is necessary to accumulate materials on the distribution of impurity elements, sometimes not playing a role in assessing the industrial importance of deposits, but leading to the emergence of various man-made geochemical anomalies in areas of exploration and mining operations, as well as the formation of man-made deposits in places of waste storage of concentration plants and metallurgical plants.
