Experience in the use of the fertile soil layer for the reclamation of non-ferrous metallurgy waste (Kemerovo region)

Abstract

The article shows the results of experiments on biological reclamation of a pilot production site. Wastes from hydrometallurgical processing of clinkers from the Belovsky zinc plant (Kemerovo region) were chosen as objects. Various approaches were considered, in which the technogenic soil and its mixture with a humus substrate were sown with yellow sweet clover and awnless brome. As a result of the analysis of samples, the degree of soil acidity, cation exchange capacity, fractional composition, concentrations of mobile phosphorus and potassium, organic carbon, and the content of mobile forms of elements in an acetate-ammonium buffer solution were determined. The results obtained were evaluated according to agrochemical gradations and hygienic standards. The conducted studies allow us to conclude that technogenic soil is a substrate with unfavorable physical and agrochemical properties. Mixing man-made soil with a fertile soil layer does not improve its properties.
