Abstract

The factors which control the rate of dissolution of pure gold in cyanide solution were studied both directly and through measurement of the current-potential curves for the anodic and cathodic portions of the reaction. The mechanism of dissolution is probably electrochemical in nature, and the rate is determined by the rate of diffusion of dissolved oxygen or cyanide to the gold surface, depending on their relative concentrations. The significance of the results and the effects of impurities are considered.
