| 摘 要： | 为防治矿山尾矿造成环境污染，对方铅矿，闪锌矿，磁黄铁矿、黄铜矿，黄铁矿进行了风化氧化实验研究，结果显示，硫化物的氧化速率顺序为：方铅矿＞闪锌矿＞磁黄铁矿＞黄铜矿＞黄铁矿，侵蚀液pH值越低，硫化物氧化速率越大，有机物存在对硫化物氧化起缓冲和抑制作用。

| Abstract: | The weathering and oxidation of sulfides within mine tailings lead to acid drainage and release of heavy metals, which pollute ground water and surface water and damage ecological environment. Recent researches show that many factors can affect weathering of mine tailings. This paper points out that grain sizes, pH values and concentrations of organic matters in mine tailings can affect weathering and oxidation of sulfides. The qualitative observation and quantitative test of sulfides with optic microscope indicate that the rate of oxidation follows the sequence of PbS>ZnS>Fe 1-x S>CuFeS 2>FeS 2 within sulfides of the same grain size. The experimental results also suggest that organic matters in mine tailings can prevent sulfide minerals from weathering and oxidation. |
