It was found in the work that pyrite present in ores actively interacts with iron (III) salts in solution according to the reactions: 2FeS 2 +7O 2 +2H 2 O = 2FeSO 4 + 2H 2 SO 4 FeS 2 +14 Fe3++8H 2 O=15Fe2++2SO 4 2-+16H+; FeS 2 + 2 Fe3+= 3 Fe2++ 2S0. The mechanism of interaction of organic matter with iron (III) salts in solution is revealed.
