The　steel　manufacturing　process　involves　not　only　the　substance　flow　of　iron　from　iron-bearing　materials　to　steel　products　but　also　the　circulation　and　movement　of　many　additional　elements.　In　this　study,　the　flow　and　circulation　of　zinc　during　coking,　sintering,　blast　furnace　(BF)　ironmaking,　basic　oxygen　furnace　(BOF)　steelmaking,　and　continuous　casting　processes,　which　has　been　neglected,　was　analyzed　in　an　integrated　iron　and　steel　mill　throughout　2013.　The　results　indicated　that　approximately　2,317　tonnes　(t)　of　zinc　from　steelmaking　raw　materials　were　input　into　the　studied　steel　mill　in　2013,　of　which　58.8%　originated　from　iron　ore　fines,　22.3%　from　pellets,　and　8.8%　from　lumps.　Although　1,212　t　of　zinc　was　discharged　along　with　coking　chemical　products　and　steel　slag　after　magnetic　separation　or　iron-bearing　dust　and　sludge,　1,105　t　of　zinc　remained　within　the　circulation.　According　to　this　research,　we　inferred　that　approximately　142　kilotonnes　of　zinc,　2.7%　of　China＇s　zinc　production　in　2013,　and　approximately　1.5　million　tonnes　in　total　from　2000　to　2017　were　concentrated　in　BF　and　BOF　dust　or　sludge.　This　large　amount　of　zinc　has　been　ignored　by　Chinese　steelmakers　and　zinc　producers,　although　it　should　be　used　as　a　resource　for　zinc　recycling.　Thus,　integrated　steel　mills　should　develop　pertinent　treatments　targeting　these　fractions　to　prevent　and　handle　the　hazards　from　the　circulation　and　concentration　of　zinc　inside　their　premises.
