摘 要: 对河台金矿尾矿库中尾矿、尾水及生长植物进行采样分析 ,研究了尾矿库剖面中金属硫化物的环境地球化学效应 ,结果显示金属硫化物的化学风化作用呈规律性变化 ,从而导致尾水的 p H值降低 ,游离态重金属离子浓度增加。通过对水生植物凤眼莲和尾矿坝上的植物蜈蚣蕨的分析发现 。 In the paper, the samples of tailing, wastewater and plants in Hetai gold mine have been collected and analyzed for their environmental geochemistry effect on the tailing profile. The results show that the chemical weathering of metal sulfide is changing regularly, which caused reduction of pH of the wastewater and dissociate ions of heavy metal increasing. It is discovered that the water plants of Euphoria Crassipes and Pteridophy can respectively enrich a great deal of As and Cu in the poisonous environment of gold mine.
