FIELD: mining.
SUBSTANCE: separation of tailings into fractions is performed at tailing drain points on inclined surface, on which system of settling trenches with reinforced-concrete trays laid in them is created. Width of the tray bottom is equal to width of bucket of extraction-loading equipment. Then, mechanical cleaning of settling trenches from conditioning tailings is performed.
EFFECT: reduction of impoverishment of tailings and costs for development of useful components.
