A　middle　grade　siliceous　phosphorite　from　Yunnan　province　was　selected　to　treat　Cd2+　bearing　aqueous　solutions.The　siliceous　phosphorite　was　tested　by　X-ray　fluorescence　spectrometer,　X-ray　diffraction,　infrared　spectrometer　and　scanning　electron　microscopy.　The　results　present　that　the　valuable　mineral　is　nanostructured　carbonated　fluorapatite　and　the　major　gangue　mineral　is　quartz.　The　amount　of　Cd2+　sorbed　by　the　siliceous　phosphorite　tends　to　increase　with　the　increase　of　initial　pH　or　the　initial　Cd2+　concentration　of　the　simulated　waste　water.　The　reaction　process　of　Cd2+　removal　from　aqueous　solutions　is　highly　fitted　with　the　pseudo-second　order　kinetic　model.　The　results　indicate　that　nanostructured　carbonated　fluorapatite　bearing　siliceous　phosphorite　can　effectively　immobilize　aqueous　Cd2+.　©　(2013)　Trans　Tech　Publications,　Switzerland.
