Gold Recovery from WEEE by Chlorine System
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 ofEEEs (WEEE) that presents a new environmental challenge.The results show that the best recovery of gold can be obtained via aqua regia (3HCI=HNO3),with concentration of 1/10 gr/L.The reaction temperature has little effect on the extent of extraction.
