Abstract：

Lead　and　zinc　mine　tailings　contain　a　variety　of　heavy　metals,　which　may　leach　in　certain　circumstances　and　cause　serious　pollutions.　In　this　work,　we　investigated　the　basic　characteristics　of　lead-zinc　tailings　such　as　gangue　minerals,　chemical　composition,　heavy　metal,　organic　matter　content　and　pH.　Based　on　these　results,　the　leaching　behaviors　of　heavy　metal　under　different　pH　with　and　without　nano-CeO2　used　as　adsorbent　of　heavy　metal　were　researched.　The　optimal　amount　of　nano-CeO2　and　the　effects　of　pH　on　the　adsorption　were　also　studied　carefully.　It　is　evident　that　the　dissolution　capacity　of　heavy　metal　is　decreased　with　the　increase　of　pH.　The　optimal　dosage　of　nano-CeO2　is　0.5wt%　mine　tailings.　Furthermore,　when　the　pH　is　in　the　range　of　5-8,　nano-CeO2　exhibits　high　adsorption　rate　of　heavy　metal.　In　this　regard,　this　work　provides　a　solution　for　reducing　the　pollution　of　lead　and　zinc　tailings.　©　2017,　Chongqing　Functional　Materials　Periodical　Press　Co.　Ltd.　All　right　reserved.
