Integration of Hyperspectral Imaging and Geometallurgy

This talk covers the integration of hyperspectral imaging in geometallurgy. Imaging spectroscopy (aka hyperspectral imaging) is an important and powerful tool for mineral identification. Effective mineral identification using imaging spectroscopy is dependent on many factors. A mineral’s absorption features wavelengths, grain size, and the scale of imaging spectroscopy measurements are important considerations along with environmental constraints. In addition to scale, data availability, cost, spectral resolution, signal-to-noise ratio (SNR) impact the data selection process. These considerations lead to image processing, analysis, and interpretation focused on mineral identification, followed by integration and modeling with other geological, geochemical, metallurgical, and mineral processing data to satisfy the geometallurgical objective.
