Abstract: A Method for Selective Separation of Precious Metals from E-Waste and Spent Nickel Catalysts ABSTRACT The present invention discloses methods for the selective recovery of precious metals from electronic waste (e-waste). An environmentally friendly oxidizing agent is developed for the selective oxidation and separation of copper from printed circuit board (PCB) metal powder. Additionally, selective recovery of gold and silver is achieved using fluxing agents. Following selective leaching, copper is recovered from the leach solution through cementation with more active metal species. Impurities, such as aluminum (Al) and iron (Fe), are subsequently removed via pH precipitation. The remaining leached elements are further separated using crystallization or additional pH precipitation processes. Reference Fig: Fig. 1
