Low-cost sorption technologies for large-tonnage wastewater treatment in mining industries

Abstract

Abstract The current state of water bodies in the zone of influence of the largest mining complexes in Russia – JSC “Apatit” and JSC “Kovdorsky GOK” was assessed on the basis of the conducted monitoring studies. The review of the natural and artificial materials with the high sorption capacity was carried out on the purpose of elimination of the revealed sources of hydrochemical anomalies. The paper presents the laboratory test results of sorbents depending on the methods of their modification, composition and properties of purified water. The introduction of developed sorbents into the wastewater treatment systems will significantly reduce the negative impact of the mining enterprises on surface waters, thus it will improve the environmental situation in the studied areas and the life quality of the local community.
