FIELD: mining industry; applicable in storing of multicomponent rock mass. SUBSTANCE: the method includes formation of drainage layer 1, concentrated layer 2 and leaching layer 3. Concentrated layer 2 is formed of gold-containing pyrites in mixture with sulfides which do not contain gold. Treatment of leaching layer with chlorine-containing solution from source 4 results in leaching, migration and precipitation of gold in concentrated layer 2 exclusively on pyrite. For this purpose, gold concentration in solutions should not exceed values indicated in the invention description. EFFECT: higher efficiency. 4 cl, 1 dwg |
