The　acid　mine　drainage　(AMD)　formed　during　copper　mining　and　smelting　has　a　low　pH,　high　sulfate　concentration,　and　large　amounts　of　valuable　metals　such　as　Fe,　Cu,　and　Mn.　In　order　to　achieve　step-by-step　recovery　of　these　resources,　it　is　necessary　to　first　remove　high　concentrations　of　iron　from　the　wastewater.　In　this　study,　chemical　oxidation　technology　was　applied　to　establish　a　12　m(3)/d　pilot-scale　treatment　process　to　precipitate　high-concentration　iron　(510.3　+/-　50　mg/L)　under　acidic　conditions.　The　experimental　results　showed　that　the　Fe2+　oxidation　rate　and　TFe　(total　Fe)　removal　rate　exceeded　99%,　while　the　loss　of　Cu　and　Mn　did　not　exceed　4%.　The　average　Fe　content　of　the　recovered　sludge　was　26.85%,　which　signifies　good　recycling　value.　In　addition,　an　economic　analysis　showed　that　this　method　was　14　cents　cheaper　per　m(3)　than　the　traditional　lime　neutralization　method　for　treating　AMD,　which　would　result　in　large　annual　savings　for　sludge　treatment　costs.
