| 摘 要： | 硫化物是自然界中常见矿物，在铅锌矿床中分布极其广泛（如黄铁矿、闪锌矿和方铅矿等），矿产资源的开采利用，使其大量暴露于地表，与Fe^3＋、溶解氧等发生氧化作用，释放出大量酸性废水（AMD）和重金属元素等有害物质，导致局部表生地球化学异常和环境污染。因此硫化物矿物氧化动力学实验研究对于表生成矿作用和矿山环境污染治理方面具有... |

| Abstract: | Sulfide minerals are present in a large number of natural environments,especially in Pb-Zn deposits,and are exposed on the Earth′s surface in the course of exploration and utilization of ore deposits.The mineral react with oxidants(such as Fe3+,dissolved oxygen),then leading to drainage of acid minerals(DAM) and release of heavy metal elements,thus causing hypergene geochemical anormalies and environmental pollution.So,kinetic experimental studies on oxidative reaction of sulfide minerals are very important for hypergene ore deposits and for prevention of mining environment pollution.In this paper,we have discussed the situation and progress of kinetic experimental studies on oxidative reaction of sulfide minerals,and pointed out the development orientation of oxidative kinetics research on sulfide minerals. |
| Keywords: | sulfide mineral oxidative reaction rate-controlled step affecting factor hypergene condition |
