Active hyperspectral mineralogy sensing for mining

Abstract

According to an example aspect of the present invention, there is provided a method for active hyperspectral mineralogy sensing during a Run-of-Mine in field conditions, wherein the method comprises illuminating a point on a surface of a mining material with a first broadband light signal having a range of illumination within a wavelength range of about 1350 and about 2500 nm, to enable the determination of information related to at least one water-related, carbonate-related or hydroxide-related absorbance feature, receiving a reflected version of the first broadband light signal, wherein said reflected version of the first broadband light signal is a reflection from the mining material at different wavelengths within the range of illumination of the first broadband light signal, determining a reflectance spectrum of the point of the mining material based on said reflected version of the first broadband light signal and further determining said information related to at least one water-related, carbonate-related or hydroxide-related absorbance feature based on the reflectance spectrum and performing qualitative and quantitative mineralogy analysis based on said information related to at least one water-related, carbonate-related or hydroxide-related absorbance feature.
