In this study,the cyanide tailings from a gold production enterprise were used as the research object,and 6 single methods and joint processes were used for treatment to determine the best treatment process and para-meters.The results showed that hydrogen peroxide＋ozone oxidation,and activated carbon catalytic oxidation treatments can treat cyanide tailings to meet the requirements for tailings dam disposal and backfilling in HJ 943-2018 Technical Specification for Pollution Control of Cyanide Leaching Residue in Gold Industry and recover valuable metal elements from the tailings.This provides a process reference for the treatment of cyanide tailings.
