Geochemical and mineralogical characterization studies play an important role in the definition of mineral deposits. Each mineral system has a unique set of minerals with different chemical makeup and physical properties. Platinum-group elements (PGEs), for example, are scarce resources with many applications. The optimization of extraction process efficiency is therefore crucial to prevent resource shortage and increased bulk prices. To improve the mineral liberation process, high throughput sensors must be added alongside the production line as part of fast process analysis implementation. Current analytical methods are either ineffective to assess PGE content, or unusable in the conditions of the processing facilities. This article shows how Laser-induced breakdown spectroscopy (LIBS) technology, developed by ELEMISSION Inc, can circumvent these drawbacks by enabling automated, ultra-fast, and precise quantitative mineral analyses in any working environment. The drill core samples that were used in this study were collected at the Stillwater platinum group element mine in the United States. The data used for the mineralogical database was validated using the TESCAN Integrated Mineral Analyzer (TIMA) instrument.

利用CORIOSITY激光诱导击穿光谱（LIBS）系统进行超快速自动矿物相识别和定量分析的新技术的出现

地球化学和矿物学表征研究在矿床定义中起着重要作用。每个矿物系统都有一组独特的矿物，这些矿物具有不同的化学组成和物理特性。例如，铂族元素（PGE）是许多应用程序中的稀缺资源。因此，提取工艺效率的优化对于防止资源短缺和价格上涨至关重要。为了改善矿物释放过程，必须在生产线旁边添加高通量传感器，作为快速过程分析实施的一部分。当前的分析方法要么无法有效评估PGE含量，要么无法在加工设施的条件下使用。本文介绍了ELEMISSION Inc.开发的激光诱导击穿光谱（LIBS）技术如何，通过在任何工作环境中实现自动化，超快速和精确的定量矿物分析，可以避免这些缺点。本研究中使用的钻芯样品是在美国的斯蒂尔沃特铂族元素矿中采集的。使用TESCAN集成矿物分析仪（TIMA）仪器验证了用于矿物数据库的数据。
