【摘要】：煤中稀土元素(REE)可以提供丰富的沉积环境与物源信息,同时也是潜在的稀土元素矿产资源。运用电感耦合等离子体质谱仪(ICP-MS)、场发射扫描电镜(SEM)、X射线荧光光谱方法(XRF)和X射线衍射方法(XRD),对豫西裴沟矿二_1煤层中稀土元素含量、分布与赋存特征进行了研究。结果表明,该煤层(50)REE含量范围为22.15~278.45μg/g,平均为90.68μg/g;稀土元素的赋存与无机组分相关,与黏土矿物特别是高岭石关系最为密切;稀土元素在不同分层样品中的含量差异显著,成煤后剧烈的构造运动和煤体变形对稀土元素的含量与分布没有明显影响;部分煤分层中稀土元素的含量已经达到工业开采品位,具有潜在的开发利用前景。
[Abstract]:REE) can provide abundant information of sedimentary environment and provenance, and it is also a potential mineral resource of rare earth elements. By means of inductively coupled plasma mass spectrometer (ICP-MS), field emission scanning electron microscopy (SEM) and X-ray diffraction (XRD), the contents, distribution and occurrence characteristics of rare earth elements in coal seam No. 1 of Peigou Mine, Western Henan Province, are studied. The results show that the REE content ranges from 22.15 渭 g / g to 278.45 渭 g / g, with an average of 90.68 渭 g / g, and the occurrence of rare earth elements is closely related to inorganic components, especially to clay minerals, especially kaolinite, and the content of rare earth elements in different stratified samples is significantly different. The severe tectonic movement and deformation of coal body after coal formation have no obvious influence on the content and distribution of rare earth elements, and the contents of rare earth elements in some coal layers have reached the grade of industrial exploitation, which has the potential prospect of exploitation and utilization.
