The application discloses an oxygen-sulfur mixed zinc concentrate oxygen-sulfur separation agent JH-3000 and a preparation method and application thereof. The oxygen-sulfur mixed zinc concentrate oxygen-sulfur separation agent JH-3000 is composed of glycerol trioleate, glycerol monostearate, trimethylolpropane trioleate and sorbitan monostearate. The oxygen-sulfur mixed zinc concentrate oxygen-sulfur separation agent JH-3000 is a dispersant composed of glycerol trioleate, glycerol monostearate, trimethylolpropane trioleate and sorbitan monostearate. The dispersant has low surface energy. After being added into ore slurry, the dispersant can disperse the mineral processing reagent on the surface of minerals. The mineral processing reagent migrates to the surface of the dispersant, changes the stable state of the mineral processing reagent, reduces the adhesion of the mineral processing reagent, and further makes the mineral processing reagent more easily dispersed from the surface of the minerals.
