摘要
Abstract
TailingsampleswerecollectedbydrillinginNo.1tailingdamfromtheDexingmine.Themulti-elementanalyticalscheme wereapplied.Thetailingsizewasdeterminedbythelasergrainsizeanalyticalinstrument,andthemineralformwasdeterminedbyX-raypowderdiffractometry.Someconclusionshavebeenreached:Themajorparticlesofthetailingaresilty,withquartzandsericiteas themainminerals,whilethecontentofmetalmineralsislessthan1%.Thewater-sortingactionandsupergenegeochemicalprocessin thetailingdamcombinedwithchangesinoregradeandmineralprocessingcausedunevendistributionofelementsandparticlesizesof tailing.Thetailingparticlesizedecreasesinthedirectionofthetailingdischarge,andtheelementscanbedividedinto3zones:Cu, Fe,Mo→SiO2,Au→Al2O3,Tl.Duringthesupergenegeochemicalprocess,thesulfidewasweatheredintooxides,whichledtothe significantdecreaseofthepyritecontent,withthelossofCu,Mo,S,Fe,CaandCintailing.Meanwhilesericitechangedintoillite.关键词
