METHOD OF GEOTECHNOLOGY TREATMENT FOR SULPHIDE ORE CULL, CONTAINING HEAVY METALS

FIELD: mining. ^ SUBSTANCE: invention concerns physicochemical geotechnology particularly, treatment of sulphide ore cull, containing heavy metals and can be used at open-cast ore concentration. In the basis of facility it is located anti-filtering and drainage layers. At drainage layer it is located leachable layer made of sulphide ore cull. Concentrated layer contains of independent sections row located along the strike of concentrated layer, each of them is separated for row of sequentially located areas. Areas of ach section are implemented as autonomous, outfitted by anti-filtering and drainage layers and hydraulically connected to each other sequentially. After layers forming installation implements activation of leached layer by means of its occasional irrigation by leaching solution, in the capacity of which there is used water or 1-3% solution of sulfuric acid. Irrigation period is accepted equal to 1.0-1.5 days. ^ EFFECT: effectiveness increase of sulphide ore cull treatment method. ^ 11 cl, 4 dwg, 2 ex
