Abstract: In many countries and regions, acid mine water drainage leads to serious environmental pollution. Mine water sources are very diverse, and therefore it is not always possible to unambiguously define «typical mine water» for individual deposits. Even in one geological structure, incomparable hydrochemical water mixtures can be distinguished. The types and therefore the chemical composition of mine waters within the same mining company often differ in time and space. It also changes along with the advancement of winning operations in depth, it changes depending on the amount and composition of natural sources of mine water during a given period of production, etc. In operating mines, the chemistry of mine water changes along with the mixing of different types of mine water contaminated with various substances. products of weathering, products of bacterial and biological decomposition, etc. In addition, the cessation of mining operations greatly changes the regime of mine waters. In this case, one of the sources is turned off – industrial and technological water, and the mine water takes on the character of water from old workings. The article describes the source and mechanism of formation of acidic wastewater from mining enterprises, provides characteristics of several methods of their treatment. Some widely used technologies and principles of acid wastewater treatment are analyzed, and the main treatment methods are highlighted: flotation method of sulfide precipitation, displacement method, extraction method, combined treatment method and biochemical electrode method.
Keywords: acidic mine waste water, formation mechanism, treatment principle, treatment.
