| 摘 要： | 在煤矸石的静态淋溶试验的基础上。研究了7-种有害微量元素的淋溶特性，分析了微量元素析出的影响因素。结果表明，淋溶液最终pH呈弱碱性：元素溶出浓度与淋溶时间，淋溶温度，煤矸石粒径，淋溶液pH值以及元素在煤矸石中的含量，赋存状态、本身性质有密切关系。

| Abstract: | Based on a static leaching experiment of gangues, leaching characters of seven hazardous trace elements were studied, and factors affecting the leaching-out of trace elements were analysed. The result has shown that the final leaching liquor is weakly alkaline, and leachable contents of the hazardous trace elements from gangues were closely related to leaching time, leaching temperature, grain size of gangues, pH value of the leaching liquor, and the content, form and properties of the trace elements in gangues. |
