摘要：The article presents the data based on the long-term observations of the Lomonosov mine tailing storage impact on the natural environment.Study of the chemical, mineral and phase composition of waste, sampled at the tailing site, was carried out.It is determined that the ore beneficiation waste in the Lomonosov deposit is generally represented by minerals of the smectite group.According to the X-ray diffraction analysis data, the beneficiation wastes are a bi-mineral mixture of montmorillonite and talc with pyrophyllite impurities.Wastes of this composition are potentially magnesia raw materials used in the production of construction materials, such as cement, ceramic bricks, etc.Experimental studies have justified the use of the method of wastes recycling based on the roasting of the ore beneficiation tailings, with the number of process options, depending on the temperature regimes and the exposure time.
