The kinetics and mechanism of adsorption of gold and silver from thiourea solution with activated carbon have been studied using equilibrium kinetic analysis. The intra-diffusion properties were determined and the kinetic and thermodynamic constants were calculated. The electrostatic component of the adsorption reaction was estimated by electrochemical studies. The optimal parameters for the desorption of noble metal thiourea were determined. By using active additives in the eluent and electrochemical polarization of activated carbon, the desorption of gold and silver is enhanced. Found the activated carbon from thiourea solution or pulp complexation and selective extraction of gold and silver.
