| Summary: | Relevance. Mining production became «the recognized leader» in the impact on the environment, including the destruction of the earth's surface when mining, with catastrophic consequences. Minimizing harmful effects of mining technologies becomes a topical area of research at the global scale, but there is no practical solution on the way out of the situation. The aim of the study is to prove the ecological-economic efficiency of nature protection and resource-saving technologies of mining ore deposits of solid minerals and to substantiate their prospects. Methods of the research include analysis and synthesis of results of theoretical and experimental research carried out before, literature and patent data. Results. The paper introduces the historical information on the dynamics of mining industry evolution. It is shown that natural and anthropogenic factors of destruction of ecosystems increase each other due to synergetic effect. The authors have identified the areas of risk reduction: laying the technological voids with hardening mixtures; in situ leaching of poor and orphaned ores; heap leaching of low-grade ores; leaching of tailings of beneficiation and metallurgy of activated processes in activator-type disintegrator. Disposal of ore primary processing tailings after extracting metals to the level of sanitary requirements by combining chemical enrichment and activation is recommended as the perspective direction of solving environmental problems. Conclusions. Disposal of tailings is the real direction of survival of the technologically rich region of extraction and processing of mineral raw materials in the context of unpredictable technological advances, solving the problem of hardening mineral-raw material base ofmining enterprises and environmental conservation from degradation. |
