This work compared the effect of nitric acid and chloride acid systems on dissolving precious metals of Electrical and Electronic Equipments (EEE). As a result of the revolution of informatics technology, the production of EEE is rapidly increasing in the world. Due to economic growth, technological innovation and market expansion of EEE there is a significant increase in waste of EEEs (WEEE) that presents a new environmental challenge.The results show that the best recovery of gold can be obtained via aqua regia (3HCl=HNO3), with concentration of 1/10 gr/L. The reaction temperature has little effect on the extent of extraction. |
