ECOLOGICAL HAZARD OF ACCUMULATED MINING WASTE AND RECOMMENDATIONS ON RISK REDUCTION IN THE FAR EASTERN FEDERAL DISTRICT

The article presents the results of the long-term experimental studies into the ecological hazard of accumulated mining waste in the Far Eastern Federal District. The studies are aimed to develop a scientific framework for the integrated assessment of influence exerted by tin mining and processing waste on ecosphere towards elaboration of practical procedures on improvement of ecological situation in the studied region. It is found that tin processing waste is highly toxic, which undoubtedly contributes to contamination of the environment. This inference is backed with the acid value of the waste (pH 4–5), which governs extensive mobility of metals. The experimental studies carried out within the limits of influence zone of a tailings pond prove deep involvement of toxic chemical elements from waste in the geochemical circulation. Based on the integrated assessment of influence exerted by mining and processing waste on ecosystems, the methods and means towards ecological and social safety are proposed, and their novelty is proved by the Russian Federation patent.


The study was supported by the Russian Science Foundation, Project No. 15-17-10016, and by the Pacific State University.
