To　develop　a　rational　strategy　involving　the　consolidation　of　Pb-Zn　mine　tailings　to　produce　the　building　materials,　Pb-Zn　mine　tailings,　together　with　different　amounts　of　silica　fume　and　cement,　were　used　to　fabricate　the　unburned　bricks.　The　influences　of　silica　fume　and　cement　on　the　consolidation　of　heavy　metal　ions,　were　investigated.　The　adsorption　behaviors　unburned　bricks　toward　the　Pb　2+　in　wastewater　under　different　conditions　(pH,　contact　time,　and　initial　concentration)　was　also　studied　by　using　X-ray　fluorescence　spectrometer,　inductively　coupled　lasma　atomic　emission　spectrometer,　and　scanning　electron　microscope.　The　results　show　that　MU20　unburned　bricks　can　be　achieved,　when　the　content　of　Pb-Zn　mine　tailing　and　silica　fume　are　70%　and　20%,　respectively.　Meanwhile,　the　hydration　products　can　effectively　immobilize　the　heavy　metal　ions　by　forming　the　sediment　with　them.　Therefore,　the　unburned　bricks　have　efficient　removal　ability　toward　the　Pb　in　wastewater,　and　can　be　used　as　adsorption　substrates.　The　Pb　2+　adsorption　efficiency　can　reach　up　to　96%,　when　the　pH,　contact　time,　and　initial　concentration　are　5,　90　min,　and　50　mg/L,　respectively.　Therefore,　a　proper　amount　of　silica　powder　and　cement　can　improve　the　Pb　2+　adsorption　ability　of　unburned　bricks　made　from　tailings,　enabling　them　promising　for　applicationsin　river　banks.　©　2016,　Editorial　Board　of　Material　Science　and　Technology.　All　right　reserved.
