Measuring the concentration of gold in ore samples by laser-induced breakdown spectroscopy and comparison with the gravimetry/atomic absorption techniques

Using a calibration model built from 14 compressed powders of reference materials doped with gold in solution, the gold concentration of 32, 6-sided, ore samples was determined by LIBS and then compared to those obtained by conventional laboratory techniques (gravimetry/atomic absorption). The studi...
