FIELD: mining industry. SUBSTANCE: method for bacterial leaching of sulfide ores, mixed ores, oxidized ores, concentrates and wastes involves treatment of raw materials with aqueous acid composition containing autotrophic acidophilic bacteria. The composition is supplemented with barbiturate. The process involves continuous cultivation of bacteria, and the composition is heated. Phenol barbital is used as barbiturate. EFFECT: higher rate of process. 4 cl
