| Abstract: | The improved elecrokinetic technique was used to remove heavy metals from lead-zinc mine tailings.The results show that the total removal rates of Pb,Zn and Cu are 34%,33% and 37% respectively after the electro-remediation for seven days.The removal rates of acid extraction fractions of Pb,Zn and Cu are 66%,86% and 81% respectively.The removal rates of oxide fractions of Pb and Cu are 39% and 42% respectively.The removal rates of other fractions are only about 10%. |
