The invention discloses a zinc-selecting reagent composition for lead-zinc sulfide ores and a zinc-sulfur separation ore-dressing method, wherein the zinc-selecting reagent composition for lead-zinc sulfide ores is used for being added into lead-selecting tailings and comprises the following reagents: 200 portions of sodium sulfite, 200 portions of sodium bisulfite combined agent, 600 portions of copper sulfate and 10 to 40 portions of ethionamide. The invention adopts the new medicament combination to realize the process of preferentially selecting zinc and then selecting sulfur under the condition of natural pH value of ore pulp, the beneficiation wastewater is neutral, the wastewater treatment cost is reduced, and the environmental protection is facilitated. |
