TAILING DUMP Russian patent published in 2024 - IPC E02B7/06 

FIELD: mining.

SUBSTANCE: invention relates to mining industry and can be used as a structure for storage of dressing tailings having low density and high fluidity. Problem is solved by the fact that the tailing dump, including enclosing dam 1 and filtering dam 5, is equipped with a recycling water supply system, tailings treatment station 4, located on the section of main pulp line 15, wherein infiltration screen 6 is arranged on filtering dam slope surface while anti-filtration screen 10 is arranged on upstream slope surface of enclosing dam 1 within limits of clarified water deep-water pond zone 8. Invention makes it possible to increase efficiency of water clarification by means of liquid phase separation from solid phase of tail pulp at processing of ores, which cause low density and high fluidity of dressing tailings, with maximum retention of water in circulation. Wind effect on water in the pond is reduced, since the surface area of the water surface and the amount of free water in the compartment with the solid phase of the dressing tailings are considerably reduced.

EFFECT: increased efficiency of water clarification under conditions of ore processing, which cause low density and high fluidity of dressing tailings, and its maximum preservation in circulation.
