The invention relates to a zinc-containing cyanide barren solution treatment method. The method comprises technological steps and conditions as follows: step one, sulfuration and acidification reactions: firstly, soluble sulfide is added to the zinc-containing cyanide barren solution, then concentrated sulfuric acid is added for the acidification reaction, the pH value of a solution is regulated, PAM (polyacrylamide) is added, a product is left to stand and precipitate and then subjected to solid-liquid separation I, dregs I, tail gas and a supernatant are separated out, and the dregs I are conveyed to a zinc smelting enterprise for integrated recycling; step two, neutralization and sedimentation: alkali is added to the supernatant produced in the step one, the pH value is regulated to 9.0-11.5 for neutralization and sedimentation, then solid-liquid separation II is performed, dregs II and tail water are separated out, the dregs II and cyanide tailings are treated together, the tail water returns to a cyaniding system for recycling; step three, tail gas recovery: the tail gas produced in the step one is sent to an absorption tower through negative pressure, an alkali liquid is added, an absorption liquid and emptying purification gas are separated out, and the absorption liquid returns for neutralization and sedimentation. The zinc-containing cyanide barren solution treatment method has the advantages that metals such as Zn, Cu, Fe and the like in the cyanide barren solution are effectively removed, cyanides are effectively recycled, poisonous and hazardous gas is absorbed and treated, Zn and Cu in the dregs are integrally recovered, the technological process is short, the operation is simple and safe, the implementation is easy and the like, and the zinc-containing cyanide barren solution treatment method is applicable to treatment of the zinc-containing cyanide barren solution in gold smelting industry.
