| Abstract: |
| Waste printed circuit boards are not only hazardous wastes, but also important non-ferrous metal secondary resources. Seeking a clean and efficient recycling method is of great significance for protecting ecological environment, developing circular economy and realizing the "carbon peak,carbon neutral" goal of copper industry. This paper summarizes the latest research results of mechanical and physical pretreatment, incineration, pyrolysis, melting and other pyrometallurgical treatment methods at home and abroad, points out the key problems affecting their industrial application, and prospects their development trend, in order to provide reference for large-scale industrial recovery and treatment of waste printed circuit boards. |
