Previous work on gold chloride and hydroxide speciation in fluids has shown differences in opinion as to the relative importance of gold (I) and gold (III) species, as well as for the Raman peak assignments for the various ...
Raman spectra have been obtained for gold-chloride solutions at elevated temperature and pressure, with gold concentrations of 0.005 to 0.04 M and varying pH. A hydrothermal cell has been developed that allows Raman analyses ...
