“…The iPLS is a statistical method for feature selection, which is mainly used to process spectral data with multiple wavelengths (or frequencies). 22 The iPLS identifies intervals and bands that are correlated with the target variable by dividing the wavelength range into intervals and performing feature selection and modeling within each interval, and reduces the complexity of the model and improves the effectiveness of the modeling.…”

Laser-induced breakdown spectroscopy (LIBS) is a type of optical emission spectroscopy capable of rapid, simultaneous multi-element analysis. LIBS is effective for the analysis of atmospheric gases, geological fluids, and a broad spectrum of minerals, rocks, sediments, and soils both in and outside the traditional laboratory setting. With the recent introduction of commercial laboratory systems and handheld analyzers for use outside the laboratory for real-time in situ analysis in the field, LIBS is finding increasing application across the geosciences. This article first overviews the LIBS technique and then reviews its application in the domain of mineral exploration and ore processing, where LIBS offers some unique capabilities.
