Opis:: The article presents the results of hydrochemical studies of water objects, located in the impact zone of one of the largest mining enterprises in the Russian Federation – JSC “Apatite”. According to the monitoring studies, the source of surface water pollution with molybdenum was determined, geochemical assessment of the molybdenum transformation in the system “ore-bearing rocks – mine water – surface water” was performed. In order to reduce the technogenic load on the surface water located in the considered area, the way of large-tonnage mine waters purification from molybdenum was proposed. The method involves using the chemical sorbent based on waste metals. The method of sewage purification will allow solving one of the key environmental problems of the considered enterprise and, in addition, to improve the environmental situation in the considered area as well as the quality of the local population life.

Opis:: Presently, the highest level of waste generation is characterized by ferrous metallurgy enterprises, the large-tonnage wastes of which are slags of various industries. Taking into account the negative impact of slags on the environment, the limited opportunities for expanding dump volumes, as well as the depletion of sources of raw mineral raw materials, the aim of research was to develop an alternative method for the utilization of steel-smelting slags of the mining and metallurgical complex. Tthe steel smelting slag of the Novolipetsk metallurgical plant and the sewage sludge of the city water treatment station in Lipetsk were selected as the materials for the study. In the laboratory, the chemical composition of the waste was determined by means of a complex of modern analytical methods, including atomic emission spectrometry with inductively coupled plasma, X-ray fluorescence spectrometry, and atomic absorption spectrometry with electrothermal atomization. The results of the analysis enabled to assess the possibility of sharing waste as a soil additive to improve the quality of the soil. Then, under laboratory conditions, the grass mixture was grown on model soil samples with a soil additive consisting of the investigated waste with a different mass ratio. On the basis of the obtained data on seed germination, the growth of the aerial part of the biomass, the height of the leaves, and also the content of the accumulated metals in the plants, a formulation of an organomineral additive was proposed for poor soils of disturbed lands.

Tematy:: sewage

Opis:: The article presents the results of field and laboratory studies on the state of surface waters in the impact zone of one of the largest mining enterprises of the Russian Federation, i.e. Kovdor Mining and Processing Combine. On the basis of the data from the monitoring studies, the patterns of migration and transformation of manganese in the system of wastes of enrichment – surface water – are revealed. In order to solve the existing environmental problem, an effective method of treating sewage from manganese using organic sorbent based on vermiculite is proposed. The results of laboratory tests of the sorbent are described depending on the method of its modification, as well as on the composition and properties of the purified water. The proposed method of sewage treatment will reduce the negative impact of the company on surface water, thereby improving the ecological situation in the study area and improving the quality of life of the local population.
