Abstract

The mining industry is a significant factor in the transformation of the environment and a source of geochemical stress on the natural complexes of mining territories. Acidic mine waters are one of the most common and serious issues in this area. Saturated with toxic metals, they are formed as a result of sulfuric acid weathering of sulfide minerals both during mining and after its completion. The duration of acidic water formation after the closure of the mine can be several tens or hundreds of years [1]. The purification of acidic mine waters is an important environmental task [2]. The main difficulty lies in the fact that it is necessary to purify large volumes of water, which are complex multicomponent systems with low pH and high concentrations of metals and sulfates [3]. In order to avoid uncontrolled environmental impacts, these waters must be collected, and the content of polluting components must be brought up to standard values before being discharged into rivers or reused in the technological processes of enterprises.
