淋溶是有害微量元素从煤或煤矸石中析出后污染环境的重要途径。本文在对河南新密—荥巩矿区煤矸石淋溶实验的基础上 ,研究了有害微量元素从煤矸石中淋溶析出的浓度及淋溶过程中pH值的变化规律 ,探讨了不同淋溶实验方法对有害微量元素溶出的影响 ,并对有害微量元素溶出的环境意义进行了讨论
Leaching is harmful to trace elements from coal or gangue precipitated an important way to pollute the environment. Based on the experiment of leaching coal gangue from Xinmi-Gonggong mining area in Henan Province, the leaching and leaching of harmful trace elements from coal gangue were studied in this paper. The changes of pH value in different leaching experiments Method on the impact of the release of harmful trace elements, and the environmental significance of the dissolution of harmful trace elements were discussed
