The invention relates to a method for treating zinc-containing cyanide barren solution, comprising the following process steps and conditions: sulfuration acidification reaction, first adding soluble sulfide to the zinc-containing cyanide barren solution, then adding concentrated sulfuric acid to carry out acidification reaction, and adjusting the pH value of the solution , add PAM, set aside for settling, solid-liquid separation Ⅰ, separate sediment Ⅰ, tail gas and supernatant, and transport sediment Ⅰ to the zinc smelting enterprise for comprehensive recycling; to neutralize the sediment, first add Alkali, adjust the pH value to 9.0-11.5 for neutralization and precipitation, then solid-liquid separation II, separate sediment II and tail water, sediment II and cyanide tailings are treated together, tail water is returned to the cyanide system for reuse, and tail gas recovery , send the tail gas produced in the first step to the absorption tower through negative pressure, add lye, separate the absorption liquid and empty the purified gas, and return the absorption liquid to neutralize the precipitation. It has the ability to efficiently remove Zn, Cu, Fe and other metals, efficient recovery of cyanide, toxic and harmful gas absorption treatment, comprehensive recovery of Zn and Cu in sediment, short process flow, simple and safe operation, easy to implement, etc., suitable for zinc-containing cyanide barren solution in gold smelting industry Handle the application.
