Аннотация: Having analyzed the initial data of RUSAL Krasnoyarsk Aluminium Smelter, we classified 45 types of waste, determined the hazard classes and estimated annual waste accumulation to be stored and disposed of. It has been defined that 14 types of waste can be recycled and reused as constructional materials of various purposes and sorbents for industrial wastewater treatment. In this study, we subjected a lining scrap of various origin, to a complete physical and chemical analysis in order to specify the type of modification and treatment of waste, specifically lining brick scrap, in the Testing laboratory of structural materials and chemical analysis of water of the School of Engineering and Construction, Siberian Federal University, and determined the chemical composition of this waste by the X-ray fluorescence (XRF) method. We also identified the substances suitable for modification of the sorbent - the oxides of aluminium, iron, silicon, and titanium - in the optimal percentage ratio, which resulted in obtaining functional active sorbents with high technical and operational characteristics at low costs for mechanical grinding and activation. © Published under licence by IOP Publishing Ltd.
