Development of an Engineer Operation Aimed at the Reduction of Atmospheric Dust Pollution in the Decommissioning of Iron-Ore Treatment Waste

Abstract

This work covers the pollution of the atmosphere during the work of the Mikhailovsky Mining and Refining Facility which is located within 100 km from the city of Kursk, in the city of Zheleznogorsk. Over the past few years in the whole world, the anthropogenic activity, connected mainly with the locations of mineral production and those of mineral treatment and processing, has become increasingly dangerous for the natural environment. Resource development in open pits causes the formation of inorganic dust. The dust is released into the atmosphere at all stages of the enterprise's technical process. The principal sources generating inorganic dust during open mining of iron deposits include: blasting operations in an open pit, the work of transfer points, the enrichment process at a factory, pellet firing as well as dusting from the surfaces of stock dumps and dry tailings beaches.

Element Accumulation Patterns of Native Plant Species under the Natural Geochemical Stress

“…However, in the vast majority of cases, data on the response of biogeochemical reaction of plants are obtained after geological exploration, or after mining has commenced [45][46][47][48]. In this section, we discuss information about the overall reaction of plants to the deposits themselves, and man-made changes associated with exploration and mining [49][50][51][52][53][54][55][56]. In this regard, this section of the work deals with the biogeochemical features of plants tested before and after exploration (certain fields were discovered with our participation during the search by biogeochemical methods).…”
