FIELD: mining art; geo-technological methods of extraction of minerals; treatment of ores by leaching. ^ SUBSTANCE: proposed method includes saturation of ore crushed beforehand with solution followed by collection and discharge of productive solution for reworking. Crushed ore is flooded and/or washed with water activated with plasma, after which plasma-activated water is discharged and filtered and leaching solution is prepared on its base for flooding and/or washing the ore; then, leaching reaction is conducted after which leaching solution is discharged, filtered and concentration of beneficial components contained in this solution is measured; if necessary, some more leaching cycles are performed with the use of leaching solution of previous cycle till required concentration of beneficial components has been obtained. Leaching solution used for realization of this method contains plasma-activated water, reagent-solvent, pH corrector at the following ratio per 1000 kg: reagent-solvent, 1-5 kg; pH corrector, 0-2 kg; the remainder being plasma-activated water; cyanide or chlorine, or iodine, or bromine, or thiosulfate is used as reagent-solvent; lime or caustic soda is used as pH corrector. ^ EFFECT: reduced power requirements; low cost of reagents; enhanced efficiency. ^ 3 cl, 4 ex |
