The adsorption of gold from a thiourea leach solution was studied in order to evaluate the possibility of using the thiourea leach process. Many commercial ion exchange resins were used for the extraction: UR- series resins as chelating and anionic resins and Amberlites as strong and weak acid resins. The extraction of gold as the cationic aurothiourea and anionic gold chloride complexes from solution by acid cationic-exchange and base anionic resins was investigated. The effects of parameters such as PH, thiourea concentration, weight of resins, shaking time, and the presence of competing cations on the rate of extraction and the loading capacity for gold thiomrea complex, i.e. Au(CS(NH2)2)2 , are reported. Attempts were also made for understanding the involved mechanisms.
