Resumen

Gold adsorption was studied with (NH4)2S2O3, using NH4OH as pH regulator, in an ion exchange resin AuRIX®100, evaluating the adsorption stage, the experiments were carried out in batch tests and on an ion exchange column. It was found NH4OH, maximizes the adsorption of gold at pH 10.5 and the presence of thiosulfate, it is favorable for the adsorption of the gold to 99%. In column tests the adsorption is achieved to a 75% of gold. In the model of adsorption the experimental data were adjusted to the Freundlich isotherm. The AuRIX®100 resin is efficient; it has a higher capacity and fast kinetic and the results of experiments at room temperature favor the kinetic adsorption process.
