The invention discloses a regenerating method and process for recycling rare precious metals from electronic and electric wastes, and particularly discloses a process for recycling non-ferrous and rare precious metals such as copper, tin, gold, silver, platinum, palladium, rhodium and the like from electronic wastes. The regenerating method comprises the following steps of: smashing circuit boards and elements dismounted from waste electronic and electric appliances such as waste computers, waste mobile phones, waste televisions and the like to 40-200 meshes; dissolving a binder by using an organic solvent; then, separating metals and nonmetals by using a high voltage electrostatic method; next, leaching the precious metals by using sulfuric acid and aqua regia; extracting silver, gold, platinum, palladium and rhodium step by step by using a liquid membrane; and finally, carrying out purification treatment to obtain nonferrous metals such as copper and tin and the rare precious metals such as gold, silver, platinum, palladium, rhodium and the like, so that the waste secondary resource is regenerated and recycled. The regenerating method has the advantages of simplicity and convenience in process, high comprehensive metal recycle ratio, few three wastes, easiness for treatment and low cost, is a favorable technical approach for efficient utilization of mineral resources of cities, and not only has an environment-friendly benefit, but also has favorable economic and social benefits.
