Geo-electrical sections were constructed according to electrical resistivity tomography data on Shahtama tailings of Mo- ore processing plant (Transbaikal Kray, Russia), located in the permafrost zone. The capacity of technogenic deposits was determined and the zone of the fault was delineated. A wide range of electrical resistivities (ER) of mine tailings was revealed due to their different particle sizes, humidity and partially frozen condition. The statistical analysis of the distribution of resistivity of tech...

U(VI) biosorption by six natural materials: three types of peats, Polytrichium moss, EichhпїЅrnia crпїЅssipes water plant and Cladonia stellaris lichen was investigated. Natural sorbents were selected, as it is available, cheap and accessible materials. The effects of initial concentration of UO2 2- in the model radioactive solution and pH on the sorption uranyl ions were assessed. Adsorption isotherms and constants for given adsorbates and adsorbents were determined. Equilibrium is well described by Freundlich eq...

Sulfide-bearing mine tailings of the Darasun ore processing plant situated in the permafrost zone in Trans Baikal region (Russia) were examined in 2016. The composition of mine drainages and affected river waters were investigated. The processes of oxidation and chemical weathering of mine tailings leads to removal of a wide spectrum of chemical elements according to geochemical analyses. Two associations of chemical elements were found: i) Tl, Pb, Cd, Zn, Mn, and Be; ii) Cu, Mo, Au, Ag, As, and Sb. Thallium is pr...
