The CAMEVA system is based on an optical microscope in reflected light, specially adapted for allowing the acquisition of multispectral reflectance speculate in the band is visible and near-infrared, associated with a vision system that implements procedures of calibration, acquisition and correction ensuring Imaging in units of absolute reflectance with a perfect record among the different bands. This allows to recognize the metal ores in a sample with high reliability, without the intervention of an expert. It constitutes a breakthrough in the field of the geometallurgy because it provides information comparable or even complementary to the SEM (scanning electron microscopy) systems that are more advanced at a fraction of their cost, faster analysis and environmental requirements and less demanding sample preparation.
