To determine the kinetic reaction mechanism, electrochemical experimental techniques of stationary polarization, linear voltammetry and faradaic impedance were used. Gold electrodeposition experiments were realized using an electrolysis cell, provided by a rotary disk of vitreous carbon and a platinum counter electrode along with a reference electrode. An automatic measurement system was employed to obtain voltammograms and Nyquist faradaic impedance spectra. In this study, responses for different cases were analyzed through faradaic impedance criteria, considering several kinds of diagrams obtained. The influence of diffusion of aurocyanide ions and adsorption as controlling steps prior to charge transfer was verified. A proposed mechanism model is discussed for a better understanding of the kinetics involved in the gold electrowinning process.
