Efficient flotation reagent for fine-grained sphalerite separation, preparation method and application thereof

The invention discloses an efficient flotation reagent for fine-grained sphalerite separation, a preparation method and application thereof. The efficient flotation reagent for fine-grained sphaleriteseparation is composed of a sodium ethyl-xanthate solution, a sodium butyl xanthate solution, a sodium amyl xanthate solution and an ammonium dibutyl dithiophosphate solution. The preparation methodincludes: mixing the raw materials according to the formula ratio uniformly to obtain the target object efficient flotation reagent for fine-grained sphalerite separation. The efficient flotation reagent for fine-grained sphalerite separation can be applied to a complex sulfide ore separation process. The prepared reagent can be directly added for roughing operation in sphalerite flotation. The method and the collecting agent provided by the invention have obvious technical index advantages, economic benefit advantages and environmental advantages when applied to flotation process. 本发明公开了一种细粒级闪锌矿选别的高效浮选药剂及其制备方法与应用。所述的细
