| 摘 要： | 利用淋溶实验，研究了乐昌铅锌尾矿的酸化及其对重金属溶出的影响。结果表明：高硫和中硫尾矿因含很高的有效硫（分别为２０．４％和１５．９％），在尾矿的堆放过程中会发生酸化，发生酸化的时间在第５１周左右，低硫尾矿（有效硫为７．２％）在短期内不会发生酸化。尾矿发生酸化后，将促进其中盐份的溶解，从而使得Ｐｂ、Ｚｎ和Ｃｕ等重金属的溶出增高。本研究可为铅锌尾矿的环境管理提供科学依据

| Abstract: | Effects of water leaching on the acid forming and heavy metal mobility of Lechang Pb/Zn mine tailings were studied in lysimeters.The results indicated that the tailings contained high level and moderate level pyrite sulfur(20.4% and 15.9% respectively) had high acid forming potential and became acid in 51th week,and acid fication of tailings also enhance the mobility of Pb,Zn and Cu in tailings.However,tailings contained low level pyrite sulfur(7.2%)did not acidify during one-year experiment period,and water leaching had little effect on metal mobility of low sulfur tailings accordingly.The findings of present study are useful for the environment management of Pb/Zn mine tailings. |
