Mine Waters of the Mining Enterprises of the Murmansk Region: Main Pollutants, Perspective Treatment Technologies

摘要

One of the most important environmental tasks in the activities of the mining industry is wastewater cleaning. The main difficulty lies in large volumes of water. This leads to high economic and material costs in the implementation of various cleaning schemes. The priority contaminants of mine waters of two mining enterprises of the Murmansk region were analyzed: JSC Kola MMC and LLC Lovozersky GOK. Thus, for the water of Severnyi Mine, JSC Kola MMC, the main pollutants are sulfate (720 mg/L), nitrogen compounds (70 mg/L), nickel (0,35 mg/L), copper ions (0,007 mg/L), and suspended solids (25 mg/L). The priority pollutant in the mine water at Karnasurt Mine, LLC Lovozersky GOK is fluoride (15 mg/L). For each enterprise, strategies and perspective technologies for mine waters treatment were considered.
