FIELD: biotechnology.
SUBSTANCE: invention relates to microbiology, specifically to obtaining microorganisms from schungite and leaching sulphides using said microorganisms. Method for microbiological leaching of sulphides from schungite rock involves grinding schungite rock to obtain schungite powder. 1.5–2.0 vol.% of medium with schungite microorganisms is added to distilled water. Schungite powder is added to the obtained aqueous solution at ratio of 1:10 and maintained at temperature of 10–40 °C in static mode for 60–90 days.
EFFECT: method provides environmentally safe extraction of metals with increased efficiency of leaching.
