ResumoResearch and development work on a ferric chloride leach process for lead-silver containing concentrates required mapping of the PbCl2 solubility as a function of temperature and various co-electrolyte concentrations. A pycnometric sampling method was used to determine the solubility of PbCl2 and the density of the corresponding PbCl2-saturated solutions in aqueous HCl and NaCl at temperatures between 20 to 100°C. The results were fitted to a selection of parametric equations, which are presented in compact tabular and graphical forms. In addition, three-dimensional PbCl2 solubility surfaces of pseudo-binary systems as a function of temperature were generated, and some fundamental relationships were extracted from the data.
