Challenge: Distinction between Talc and Gangue
Solution: Hyperspectral Imaging for Talc Sorting
EVK HELIOS hyperspectral cameras detect the spectral differences of materials and can thus classify rocks based on their chemical composition. This allows EVK systems to be used in areas where conventional color cameras reach their limits and enables the differentiation of two similar looking rocks such as white talc and white gangue. The detection is performed directly in line and in real time for an efficient and optimized extraction process.
Hyperspectral Imaging offers the degree of classification accuracy required for applications in the mining industry by directly measuring chemical molecular composition through the absorption of light (spectroscopy).
EVK's portfolio of sensor-based technology includes hyperspectral cameras and inductive sensor systems that can be used individually or combined with a color camera with sensor fusion to create a high-performance sorting application.
