Paper Alert❗️ Hyperspectral imaging of Li-bearing minerals in underground mine

In this study we propose a workflow for using hyperspectral imaging for geological mapping in underground mining. We evaluated sensors and lighting set-ups in a lab and acquired data in a German underground mine. The corrected data were used to map mineral abundance and estimate Li content, validated with laser-induced breakdown spectroscopy. Despite challenges, this study aims to establish hyperspectral sensors in the extractive industry to increase raw material supply, advance digitalisation, and reduce environmental impact and mining risks. Take a look at the paper here: https://onlinelibrary.wiley.com/doi/10.1111/phor.12457
