Reduction of impact of mining on water ecosystems

The environmental situation in Kuzbass is governed by the anthropogenic stress typical of resource-oriented regions. The mining industry, in particular, open-pit coal mining contributes immensely to the pollution of ecosystems in this coal region. Reduction of water pollution is an urgent challenge while the current technologies of treatment of coal mine effluents are underdeveloped and approaches to purification of other types of waste water are unadapted to the specifics of the mining industry effluents. One of the ways commonly used to treat waste water of various composition is extraction by adsorption. Selection of an adsorbent and determination of an extraction mechanism or other needs an integrated approach capable to offer modeling and optimization of a water treatment process. One of the pollutants typical of waste water in open pit mines is iron. Iron migrates to effluents from different sources. The efficiency of adsorption at carbon adsorbents is demonstrated, the mechanism of mass transfer is studied using the Lagergren pseudo-first-order kinetics models and by the Marutovsky method, and the limit extraction stages are identified.
