The　disposal　of　scrap　rubber,　represented　by　retired　tires,　has　achieved　industrial　achievements,　but　the　handling　of　brass-coated　steel　wire　as　a　structural　reinforcement　in　retired　tires　has　received　little　attention.　A　feasible　and　efficient　method　of　acquiring　economical　resources　is　proposed　to　extract　copper　and　zinc　(Cu-Zn)　from　brass-coated　steel　wire.　With　20%　ammonia,　10%　hydrogen　peroxide,　and　a　liquid-solid　ratio　of　10,　the　brass　coating　almost　completely　dissolved　in　5　minutes.　This　technique　may　remedy　the　challenge　of　weak　dissolving　efficiency　brought　on　by　the　dual　phase　microstructure　of　brass.　Electrochemical　measurements　and　density　functional　theory　(DFT)　simulations　assist　in　verifying　that　hydrogen　peroxide　decreases　the　resistance　of　the　corrosion　and　that　OH-and　O-2　in　solution　are　the　main　contributors　to　the　dissolution.　In　addition,　the　AH　effectively　enhances　the　corrosion　of　the　α　phase　in　brass,　which　is　notably　evident　in　comparable　works.　This　effective　strategy　broadens　the　application　of　retired　tires　and　provides　a　new　method　for　extracting　Cu-Zn　resources.　©　2024　Korean　Society　of　Environmental　Engineers.
