| 摘 要： | 尾矿产生的重金属污染严霞影响了矿区的生态环境,在酸雨条件下,尾矿造成的重金属污染更加难以控制.本研究对大宝山尾矿进行了不同酸度(pH 5.6、pH 4.8、pH 3.0)的模拟酸雨淋溶实验,研究尾矿中重金属Cu和Zn的释放特征.结果表明:随着淋溶量的增加,淋出液pH逐渐上升,电导率呈递减趋势:Cu和Zn的释放过程均可分...

| Abstract: | Leaching experiments of tailings from Da baoshan mine with simulated acid rain(pH 5.6,pH 4.8,pH 3.0) were conducted to investigate the release characteristics of copper and zinc.The results of the experiments were as follows: with the increasing leaching volume,the pH of leachates increased gradually,but the conductivities of the leachates decreased continuously.Cu and Zn were similar in release progress,which could be divided into two stages,namely a fast leaching stage and a slow leaching stage.The accumu... |
