N2 - The master's thesis is devoted to the comprehensive utilization of iron ore tailings of JSC "Stoilensky Mining and Beneficiation Plant" by producing iron-containing coagulants and using the residues after iron recovery in the construction industry. The state of knowledge of the experience of using alternative methods of iron ore tailings reuse has been considered in detail on the basis of the scientific papers of Russian and foreign scientists. The technological part contains a description of Stoilensky Mining and Beneficiation Plant, an analysis of its impact on environmental components, as well as a description of the tailings damp. The research part contains a description of the conducted experiments to obtain and verify the effectiveness of the iron - containing coagulant, as well as a theoretical study of usage of the residues after iron recovery from iron ore tailings. The calculations were carried out on economic efficiency to prove the feasibility of the proposed project. The results showed that the implementation of the project in the enterprise pays off, and allows to reduce the negative impact on the components of the environment.
