The SiO2 in the molybdenum tailings is purified by high-temperature heating and pickling, and the surface is modified with methylhydrogen-containing silicone oil and dimethyl diethoxysilane(DDS).The results show that the impurities such as calcium and magnesium can be effectively removed, and the purified content of silicon oxide can reach 84.3%. When methyl hydrogen-containing silicone oil is used as a modifier, the activation degree of modified slag can reach 77.6%, and the maximum contact angle can reach 116°. Methyl hydrogen-containing silicone oil can be effectively grafted onto the surface oftailing particles. When dimethyl diethoxy silane is used as a modifier, the activation degree can reach 95%, the contact angle can reach 130°, and dimethyl diethoxy silaneis uniformly coated on the surface of tailing particles. The application of modified molybdenum tailings silica in ammonium hydrogen phosphate extinguishing agent shows that it can improve the water repellency of ammonium hydrogen phosphate extinguishing agent.
