With　the　development　of　society,　solid　waste,　such　as　coal　fly　ash　has　caused　serious　environmental　problems.　Extraction　of　high　value　metals　from　coal　fly　ash　is　vital　for　sustainable　development　and　maintenance　of　social　economy.　This　work　aimed　to　present　a　nonhazardous　and　efficient　electrolysis　method　to　extract　selective　iron　products　from　coal　fly　ash　leachate.　Compared　with　current　precipitation,　biological,　and　organic　extraction　processes,　this　electrolysis　method　can　selectively　prepare　different　iron　products.　No　chemicals　or　expensive　membranes　were　used　to　prevent　the　introduction　of　pollutant　and　membrane　limitations.　Moreover,　no　waste　was　produced　enabling　realization　of　zero　pollution　discharge.　Batch　experiments　indicated　that　the　degree　of　reduction　of　iron　can　be　controlled　during　the　electrolysis　process,　thereby　allowing　for　the　production　of　different　types　of　iron　products.　The　purity　of　iron　electrolytic　product　was　98.30　wt%　Fe2O3,　1.35　wt%　SO3,　and　0.09　wt%　Al2O3,　and　current　efficiency　reached　60.3%　under　the　optimal　conditions:　c　(Fe2+)　=　0.1　M,　t　=　4.0　h,　and　J　=　2500　A/m(2).　Different　iron　products　like　Fe3O4,　FeOOH　and　Fe　can　be　prepared　sequentially　during　electrolysis　process.　Moreover,　O-2　is　generated　on　anode,　and　H-2　is　generated　on　cathode　as　clean　energy,　which　increases　economic　benefits.　The　wastewater　(containing　H2SO4)　is　widely　used　as　a　leaching　reagent　during　leaching　of　coal　fly　ash,　which　can　return　to　leaching　process　enabling　zero　hazardous　substance　discharge.　This　study　would　provide　an　alternative　clean　and　efficient　method　for　extracting　selective　iron　products　from　coal　fly　ash　leachate.
