FIELD: extraction of precious metals of ore and materials comprising sulfide minerals. SUBSTANCE: method for extraction of precious metals of ore and materials involves their treatment with the help of aqueous acid composition and with the help of oxide manganese-containing material. Said treatment is carried out in the presence of bromide ion, its quantity is sufficient for conversion manganese into solution in its bivalent condition. EFFECT: higher efficiency of the method. 1 tbl
