用X射线衍射技术 (XRD)分析了重庆中梁山矿的煤系黄铁矿不同氧化程度及改性后的表面结构。根据改性前后的XRD数据 ,推导出不同电化学条件下的表面产物 ,为浮选分离煤系黄铁矿提供理论依据。
The different degree of oxidation and the surface structure of coal pyrite in Zhongliangshan Mine, Chongqing were analyzed by X-ray diffraction (XRD). According to the XRD data before and after the modification, the surface products under different electrochemical conditions were deduced to provide a theoretical basis for the flotation separation of coal pyrite.
