Abstract: A new hydrometallurgical process has been developed for recovery of gold from secondary sources such as gravitational concentrates from alluvial sands. The method consist in leaching the gold with chlorine resulted from NaClO decomposition in hydrochloric acid medium, [AuCl4]- selective recovery from hydrochloric solutions by adsorption on non-ionic polymeric resin type Amberlite XAD-7, gold elution with a mixture of organic solvent – hydrochloric acid and its reduction with an organic reducer. The gold powder is melt obtaining thus high grade (999,6 ‰) gold with a recovery yield over 98 %. The influence of the main parameters for the aqueous chlorination, the extraction and stripping data and the method for the recovery of gold f...
