Electrochemical and quartz crystal microbalance (QCM) methods were used to investigate the dissolution rate of gold in an Outokumpu HydroCopper® process solution. The measurements were conducted in an electrolyte solution where [NaCl] = 2.8 - 280 g/l, pH = 1 -2.5, [Cu 2+] = 0 -30 g/l and T = 70 -95 °C. According to these measurements the solution flow has the greatest impact on the dissolution rate of gold in the HydroCopper ® process. Under adequately acidic conditions (pH < 3), the dissolution rate of gold increases with increasing cupric concentration, increasing chloride concentration and increasing temperature. The results and trends observed compared well with the literature.
