光学显微镜鉴定、扫描电镜(能谱)及微区衍射在微量矿物检测中的联合应用

The Combined Application of Optical Microscope Identification,Scanning Electron Microscope( Energy Spectrum) and Micro-area Diffraction in Micro Mineral Detection

通过光学显微镜鉴定、扫描电镜(能谱)及微区X射线衍射分析技术的联合应用,对某铍矿物存在形式进行研究,结果表明,通过镜下鉴定、扫描电镜图像观察、能谱仪分析找出疑似铍矿物,并进行标记,之后通过微区X射线衍射对标记点进行分析,可以最终确定铍矿物种类。镜下观察、微区X射线衍射与扫描电镜(能谱)分析结合检测微量矿物的方法,具有微区、微量、原位和无损等优点,能够对在100μm尺寸以上矿物进行准确的物相鉴定。

The existing form of one beryllium mineral is studied through the combined application of optical microscope identifi- cation, scanning electron microscope （energy spectrum） and microcell X-ray diffraction analysis technique, the study results show, the sus- pected beryllium mineral shall be found through microscopic identification, the observation of scanning electron microscope images and ESEM - EDX, when the beryllium mineral is found and marked, the marked point shall be analyzed by microcell X-ray diffraction to finally con- firmed the types of beryllium mineral. The combined detection method for micro minerals by microscopic observation, microcell X-ray dif- fraction and scanning electron microscope （energy spectrum） analysis has the following advantages： micrecell, micro scale, root position, lossless, and so on, which can do the accurate phase identification for the ores that the size the over than 100μm.
