项目摘要

In a world-wide effort, Coherent Raman Microscopy (CRM) was developed for Biophotonics imaging applications. We present a unique opportunity to translate and adapt these powerful methods to Earth Sciences and Mineralogy. We are the global pioneers in the application of CRM techniques to Earth Sciences and Mineralogy, launching the new field of Geophotonics. With industry leader SGS Minerals , we will address the carbonaceous preg-robbing problem which reduces yields in Gold processing. We will supplement industry standard (slow) analytical tools with specific imaging platforms that are much faster, more flexible, robust and portable. Although spontaneous Raman spectroscopy has a long history of characterizing carbonaceous samples, it suffers from weak signals and fails when samples luminesce or fluoresce. Importantly, CRM is typically 10,000 times faster (more sensitive) than Raman and is immune to sample fluorescence. Furthermore, CRM combines rapid 3D Raman imaging with other nonlinear imaging techniques (e.g. Second Harmonic Generation) which resolve grain texture, crystallinity and morphology, further characterizing the mineral of interest. CRM comprises two techniques: Coherent Anti-Stokes Raman Scattering (CARS) and Stimulated Raman Scattering (SRS) microscopy. In Gold processing, specific carbonaceous materials will have unique Raman signatures, amorphous/crystalline properties and gold cyanide adsorption propensities. Therefore, the innovation that CRM offers is rapid, material-specific, surface and depth-resolved imaging and the potential for new real-time analytics for Gold Process Mineralogy.
在全球范围内的努力,相干拉曼显微镜(CRM)的生物光子成像应用程序的开发。我们提供了一个独特的机会,将这些强大的方法转化和适应地球科学和矿物学。我们是CRM技术应用于地球科学和矿物学的全球先驱,开创了地球光子学的新领域。与行业领导者SGS Minerals合作,我们将解决降低黄金加工产量的碳质劫矿问题。我们将用更快、更灵活、更强大和更便携的特定成像平台来补充行业标准(慢速)分析工具。虽然自发拉曼光谱具有表征碳质样品的悠久历史,但是当样品发光或发荧光时,它受到弱信号的影响并且失败。重要的是,CRM通常比拉曼快10,000倍(更灵敏),并且不受样品荧光的影响。此外,CRM将快速3D拉曼成像与其他非线性成像技术(如二次谐波发生)相结合,可解析颗粒纹理、结晶度和形态,进一步表征感兴趣的矿物。CRM包括两种技术:相干反斯托克斯拉曼散射(汽车)和受激拉曼散射(SRS)显微术。在黄金加工中,特定的碳质材料将具有独特的拉曼特征、无定形/结晶性质和氰化金吸附倾向。因此,CRM提供的创新是快速、特定材料、表面和深度分辨成像,以及黄金工艺矿物学新的实时分析潜力。
