表层覆土情况下铜尾矿典型剖面重金属富集规律研究

    Study of heavy metal concentrating rules in type copper debris section with covered soil

    • 摘要: 通过对红透山尾矿库典型剖面表层覆土以及不同深度的铜尾矿进行取样,分析测定各层的pH值和重金属全量及可交换态的变化。结果表明:在蒸发作用下,重金属元素和S随毛管水向土壤移动,并因土壤对重金属的吸附而聚集。由于淋滤-富集作用和重金属不同的理化性质,从而形成红透山铜尾矿库典型剖面重金属元素各自特殊的峰状分布规律。

       

      Abstract: Through taking sample in surface soil and different depth copper debris of type section plane of Hongtoushan and analyze change of PH value and population parametern and exchange condition of heavy metal of each layer.The result indicated:under water power potential gradient function, heavy metal and sulfur moves into surface soil layer with capillary moisture and be absorbed to concentrate in soil. And because the leaching-concentrates the function and the heavy metal different physics and chemistry nature,it forms heavy metal element respectively special peak shape distributed rule of Hongtoushan copper debris type section plane.
