Rapid mineral detection using elemental Laser-Induced Breakdown Spectroscopy (original) (raw)

The exploration and mining activities are strongly increasing both in Finland and internationally. During the exploration, rapid and on-line scanning of rock and drillcore samples gives fast results that can be used to ease the decision-making process for geologists and to guide the future drilling activities without delays. Traditional mineral exploration activities are moderately slow. Recently, faster and more efficient ore characterization by combining various laser-based and contactless measurement techniques have drawn tremendous attention in research. This combination will enable mineralogical analysis of the drillcore and recyclable materials in a fast, cost-effective and objective manner and provides complementary and partly substitutive information for the laboratory analyses. However, complexity of different measurement setups and the difference between the sources of light make it non-economic and complicated for industry. Laser-Induced Breakdown Spectroscopy is a very s...
