METHOD OF PLACING TAILINGS IN PILES ORIGINATING FROM THE METHOD OF PROCESSING IRON ORE Russian patent published in 2023 - IPC C02F11/14 C02F103/10 B03D1/08 B03D1/10 B09B3/00

Abstract RU 2808120 C2

FIELD: iron ore processing.

SUBSTANCE: invention is related to a method for placing in heaps, instead of dams, tailings produced by an iron ore processing method, which contains the stages of thickening ultra-fine tailings, thickening sandy tailings, mixing these tailings in the proportion of 80-90 wt.% of sandy tailings to 10-20 wt.% of ultrafine tailings, adding a coagulant, adding a flocculant, filtering this mixture and dumping the filtered tailings.

EFFECT: invention can be used at any iron ore concentration plant without the need for any changes in the method design.
