The invention discloses a method for comprehensively recycling valuable metals from waste printed circuit boards.The method comprises the steps that the waste printed circuit boards are smashed into particles through mechanical treatment, metal materials are separated from non-metal materials through physical separation, the metal materials are subjected to oxygen pressing and alkaline leaching to selectively recycle tin and aluminum, acidic oxidation is conducted to leach copper, and lead and noble metals are enriched in slags and recycled through a pyrogenic process.According to the method, comprehensive recycling of the valuable metals in the waste printed circuit boards is achieved, the metals are separated thoroughly, the method is clean, efficient and free of pollution, the economic benefit and environmental benefit of the electronic waste resource recovery process are both achieved, and the method is worthy of popularization.
