Leaching Law of Heavy Metals on Tailings Covered Soil
To investigate the heavy metals leaching migration law of railings covered soil and learn the possible pollution,tailings covered soil column leaching experiment was done.The results proved that,in the soil covered with tailing s,the metals leached from tailings could influenced 70cm in depth under the continuous acid rainfall condition Different elements had different transfer rates.The content of Cu was higher in tailings leached and transferred less.The transferring ability of Cr was feeblish,and it can not easily move to groundwater,and cause soil contamination.The transferring ability of Zn in soil was the biggest,and the sorption of Zn by soil was also bigger,so the content of Zn in soils and leachate was high.These elements had less influence on groundwater in a short term,but the influence of Hg,Pb should not be ignored.
