Method for in-situ rapid film formation, passivation and acid production inhibition on surface of sulfide mineral

The invention discloses a method for in-situ rapid film formation, passivation and acid production inhibition on a surface of a sulfide mineral. In a humid environment containing underground water, a biological manganese oxide is subjected to in-situ synthesizing on the surface of the sulfide mineral by using manganese oxidizing bacteria; then under the aeration condition, Fe in the surface layer of the sulfide mineral is oxidized into Fe by using a biological manganese oxide and a mixed solution containing calcium peroxide, monopotassium phosphate, sodium pyrophosphate and polyvinyl alcohol, and the Fe is further combined with PO4 to be converted into iron phosphate precipitate; therefore, an in-situ passivation film is formed on the surface of the sulfide mineral, oxidation of the sulfide mineral is avoided, and generation of acidic mineral wastewater is inhibited. According to the method, the passivation film can be quickly generated on the surface of the sulfide mineral in situ in a tailin
