FIELD: hydrometallurgy of noble metals; stage of preparation of ores of tailings of gold extraction mill and beyond-balance ore of underground mining before heap leaching of gold.
SUBSTANCE: proposed method includes preparation of ore consisting in joint nudilizing of beyond-balance ore at content of gold no less than 0.5 g/t (50%) and old tailings (50%) at addition of cement in the amount of 2-2.4 kg/t.
EFFECT: enhanced efficiency of extraction of gold from technogenious wastes at low content of gold.
