Effects of sulfur-containing mineral processing reagents on the production of sulfide from simulated lead-zinc mineral processing wastewater were studied in different conditions of reaction temperature, reaction time, pH value and stirring speed. The sulfur-containing reagents include ethyl xanthate, butyl xanthate and ethyl thio carbamate. Mechanism of sulfide producing from the reaction of xanthate, ethyl thio earbamate and carbon disulfide in mineral processing wastewater and the overproof reason of sulfide were also studied, which provided theoretical basis of over proof control of sulfide in lead-zinc mineral processing wastewater.
