Full-scale survey of the kachkanarsky industrial complex of the middle urals and assessment of its impact on the soil

The mining and processing plant, located in the area of the Kachkanar industrial hub of the Middle Urals, is mining and processing titanomagnetite iron ores from the Gusevogorskoye deposit. During the mining and processing of ores, waste is generated annually — wet magnetic separation sludge. This waste is stored in a waste disposal facility — the largest tailing dump in the Sverdlovsk Region. This tailing is a complex hydraulic structure and represents a potential hazard to the environment under its influence. The paper considers the design and specific features of this tailing dump as a waste disposal facility, as well as the process of waste generation stored in the tailing dump. This tailing dump creates specific geo-ecological conditions of the territory, and, like any object of economic activity, it has a negative impact on all components of the environment. The paper analyzes the impact of the tailings on soils affected by this waste disposal facility. The chemical composition of tailings from wet magnetic separation, stored in the tailings, corresponds to the average chemical composition of the main types of rocks present at the deposit. Wastes are mainly represented by compounds of silicon, calcium, aluminum, iron, magnesium — elements that are widespread in the earth’s crust. For a number of elements, namely, 2.8 times for vanadium, 10 times for cadmium, 1.8 times for silicon, and 2.5 times for arsenic, excesses over Clarke concentrations in the earth’s crust are observed.
