摘　　要：以兖州矿煤矸石中微量元素的淋滤作用及析出含量为例 ,分析了微量元素在洗选过程和淋滤作用下的分布、迁移规律等地球化学行为。在用不同的pH值酸性溶液作淋滤实验时发现 ,pH值对微量元素的析出影响很大。It is analyzed that geochemistry behavior of trace elements which take place during vanning and leaching in the bastard coal in the Mine of Yanzhou coal mining area.It can be found that the value of pH can affect the dropping out of the trace element from the bastard coal when using different pH values.And the concentration of the trace element in the soil has a decline trend with distance increasing from the bastard coal.
