Abstract: The paper presents the possibility to apply vibration technology for deep dehydration of processing wastes of ferruginous quartzite ores. The basic indicators of physical and mechanical properties, chemical and mineral composition of the investigated tailings are provided, which allowed to propose a device for dehydration and to justify the choice of filtering elements and the size of filter cells. The possibility of efficient separation of water and the solid phase of tailings was shown due to the effect of vibrations in the frequency range of 7 to 15 Hz, the amplitude of the vibration velocity of 0.07-0.09 m/s and the pressure drop of 0.05 MPa on the filter. The proposed solutions for deep dehydration of ferruginous quartzite tailings help to significantly enhance the level of industrial and environmental safety of their storage on the ground surface by reducing water saturation of the man-made deposits and enclosing dikes of the created man-made rock masses. Implementation of the proposed technological solutions for deep dehydration of ferruginous quartzite processing wastes into production (as exemplified by ‘Karelskiy Okatysh’ JSC) makes it possible to treat up to 65% of the incoming tailings annually.

Keywords: vibration technology, pulp dehydration, ferruginous quartzite, tailings, man-made rock masses, industrial safety, environmental safety, tailings of wet magnetic separation, properties of tailings
