FIELD: mining industry. SUBSTANCE: method for intradump concentration of tailings includes laying into prepared pit of impermeable layer, draining layer, leaching layer and concentration layer, and laying of perforated pipeline through which sulfur dioxide settling solution is supplied. Useful minerals are dissolved with leaching solutions. Metal-carrying solutions are mixed with settling solutions supplied through pipeline to form sediments. EFFECT: higher efficiency of intradump concentration of tailings. 1 dwg
