Abstract

The article is focused on the assessment of the impact of mining waste on the environment. Mining waste (MW) is understood as mine (mining) dumps and dumps of processing plants (tailings dumps). The article also suggests considering MW as technogenic deposits of rare earth and precious metals, the development of which will allow solving many environmental, social and economic problems and using natural resources in a sustainable manner. The objects under study are located on the Kola Peninsula, within the Khibiny mountain range, and are the production assets of the Apatit Mining Complex. This enterprise develops the so-called deposits of the Khibiny Tundra, it also owns apatite-nepheline processing plants.

Highlights

The relevance of the research topic is due, on the one hand, to the extremely large number of mineral deposits (MD) being developed in this country, and, on the other hand, is explained by the need for new approaches to protecting the natural environment, which is inevitably transformed during their development
Toxic elements concentrated in the Mining waste (MW), and especially in the material of small fractions of mine dumps and tailings dumps can become a source contamination source of the environment
Geochemical assessment of the grain size fractions of the MW material can be used to predict the potential threat of environmental contamination from the operation of mining enterprises

Summary

Introduction

The relevance of the research topic is due, on the one hand, to the extremely large number of mineral deposits (MD) being developed in this country, and, on the other hand, is explained by the need for new approaches to protecting the natural environment, which is inevitably transformed during their development. According to the authors, when creating mining enterprises, it is necessary to take into account the specific features of the terrain and the potential response of the natural environment to man-made impacts. This opinion of the authors develops the ideas of M.I. Agoshkov, B.N. Laskorin, N.V. Melnikov, V.V. Rzhevsky, E. It is necessary that such actions should rather be preventive and based on a scientific forecast The latter should be based on an assessment of the interrelationships of the physical and chemical processes underlying the development of minerals on the one hand and natural conditions on the other
