Scientific report: 53 pp., 10 figures, 7 tables, 130 references to primary sources. Combination of mine waters that have a high salt content and contain mechanical and organic impurities in the industry without the proper treatment almost impossible, due to the complex multicomponent and different phase composition of water. To achieve this goal is suggested the method of heterokoahulyatsiyi efficient service nanodyspersions of magnetite as a coagulant.A comprehensive overview of modern methods and technology purification and desalination of mine water showed that the physical and chemical methods for nanodyspersions of magnetite with the necessary properties are among the most promising at present. The nanoparticles of magnetite with predetermined properties, are synthesized directly in the purified solution at pH 8-11 with an aqueous solution of salts of Fe2+ and Fe3+ ratio of 1: 2 under the influence of pulsed magnetic field. Studies have shown that in the absence of surface-active substances or temperature increase to 950S or increasing the pH to 13, can not get nanosized magnetite.For nanoparticles of magnetite is proposed synthesis last under the influence of pulsed magnetic field. It is shown that the synthesis naodyspersions of magnetite in such circumstances can more fully precipitate suspended solids. Taking into account to the high affinity of uranium oxides of iron, nanomagnetite lets you use not only reduce the content of the latter to a level that does not exceed the maximum permissible concentration (MPC), but also more efficient use of electromembrane mine water treatment methods. This method of complex purification and desalination of saline mine water is characterized by efficiency, low power consumption and a high level of environmental protection.
