Gold, palladium and other precious metals are contained in electronic scrap, and their content is 2 to 20 times that of raw ore. Therefore, the development of industrial solid waste comprehensive utilization technology has great development prospects for the recycling and reuse of gold and palladium metals in electronic scrap. Currently, during the recycling process of electronic scrap, aqua regia or hydrochloric acid plus oxidizing agent is often used to leach precious metals. To ensure complete reaction, a stirring rod is usually used to stir the reactants.
