“…Increased metal concentrations-Ni (coefficient of technogenic concentration (ratio of chemical element content in the studied soil to background content) Kc = 3.7), Mn (Kc = 5), Cr (Kc = 7)-have been identified in soils of transaccumulative landscapes in the lower gleyed horizons, which are influenced by ground waters associated with the tailings area of "Mikhailovsky GOK" PJSC (ΠAO) (Kursk Region, Russia) [17].…”

“…The results of a comprehensive assessment of the technogenic impact of iron ore mining and processing enterprises on the natural and technical systems of the adjacent areas indicate a significant role of upstream tailing dumps as pollution focuses [12][13][14][15][16][17]. The liquid phase of the pulp entering the tailings dump contains significant amounts of free oxygen and carbon dioxide, creating favorable conditions for intensive leaching of tailings with the transfer to the liquid phase of a significant number of chemical elements and their compounds.…”

In terms of anthropogenic impact of mining and processing enterprises, the adjacent territories are contaminated by upstream tailings dams. The contamination is developed by active seepage of liquid waste through the body of the dams. The authors have analyzed water balance at the Kachkanar Mining and Processing Plant tailings dump (Russia, Ural Region). The company develops vanadium-containing titanium-magnetite iron ores with low ore (15%). This, along with high productivity, has determined the formation of a large number of tailings and significant amount of wastewater. The purpose of the studies is to substantiate the need to manage the seepage discharge process by means of enclosing dams to ensure environmentally safe operation of the tailings dump. The research objectives included field measurements of seepage volumes, their evaluation by computational methods and analysis of anthropogenic geochemical load on natural waters. The obtained results show an increase in seepage discharge volume from 41.91 million m3 (in 2017) to 81.44 million m3 (in 2026) as the height of the dams increases. These losses will lead to water shortages in the enterprise’s water recycling system. Calculation of pollutants in wastewater with the exception of natural component showed the leading role of technogenic factor in the content of Ti (up to 84%), V (up to 96%), Co (up to 86%) and Mo (up to 93%). Increasing the volume of seepage discharge will lead to an increase in natural water pollution within the area. Ecologically efficient management of the enterprise’s water balance is ensured by the use of tailings thickening technology and implementation of closed water supply systems.

Industrial placer gold mining creates specific montane relief shapes. The character of these landforms is influenced by the mining technology used, the management of the site and mining area, the organization of the work and the subsequent measures after the termination of mining. Available classifications of known landforms can also be partially applied to shapes created during placer gold mining. Field research was conducted on gold-bearing fields in the upper courses of the Indigirka and Kolyma rivers. Drawn and photographic documentation of sample landforms was obtained, and their dimensions were ascertained, or their genesis was observed. The landforms found often differ in character and size from shapes known from other raw material mining and industrial gold panning sites. The mining landforms created during the industrial panning of gold in Siberia are documented by drawings according to the facts found during the field research. The text presents their basic differences from the hitherto known landforms.
