矿物中化学分析检测方案(CMOS相机)

OXFORDINSTRUMENT SThe Business ofScience@Oxford Instruments 2019 工艺矿物学与化学分析 整套基于扫描电镜能谱仪(SEM-EDS) 的流程自动化的矿物学工具和其他化学分析工具 The economic viability of a mine can be determined bythe microscopic characteristics of the ore， including themineral abundance， the grain size and the degree ofore mineral liberation. It is essential to be able tocharacterise these parameters rapidly and accurately，providing the data that geologists， mineralogists andmining engineers canuse during mine feasibilitystudies and process optimisation. Energy dispersive X-ray spectrometry (EDS) in the scanning electron microscope (SEM) is the optimum tool forsuch process mineralogy， providing fast and accurate results with a high degree ofautomation. An SEM-EDS mineral liberation system can analyse both polished core sectionsand particulates from feed material and tailings， providing information that will improverecovery andidlesseni iany/ environmentaIl impact. Importantly， recent EDSS detectordevelopments have increased X-ray collection efficiency and throughput， making it possible tocharacterise samples in a matter of minutes. The image shows part of an analysis ofparticulate feed material from a zinc ore and the associated liberation curves for some of thezinc-bearing minerals. These data are then used to refine the processing parameters resultingin a more efficient extraction process and less waste. The above images show a phase map and ZnS liberation curves from the feed material in azinc mine processing plant， analysed using the Oxford Instruments INCA Mineral EDSsystem. Our x-ray sources allow tools to deliver fast an accurate in-the-field analysis of mining orechemistry to aid in in exploration and sorting of valuable minerals and metals. It’s not justunderstanding the chemistry of rocks and minerals on Earth which is important. Our x-raysources are also launch-certified and play a vital role in understanding the chemistry ofextraterrestrial material as part of ongoing explorer programs.
