Treatment of Multi-Tonnage Manganese-Containing Waste Water Using Vermiculite

Matveeva V., Danilov A., Pashkevich M.

Journal of Ecological Engineering

2018

Vol. 19, nr 1

156--162

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.

Development of Chemosorbent Based on Metallic Waste for Cleaning Mine Water from Molybdenum

Journal of Ecological Engineering

2018

Vol. 19, nr 1

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.
