Abstract

Abstract

Waste printed circuit boards (WPCBs) are a hazardous type of waste that contain valuable metal and non-metal components, due to the natural hydrophobic difference between these components, the use of flotation technology to recover them has gained widespread attention. The research progress of WPCBs flotation, including flotation reagents, enhanced flotation, flotation influencing factors, and flotation kinetics, was reviewed in this paper. It was pointed out that compared with traditional mineral flotation, WPCBs flotation has the characteristics of coarse feed size, low feed solids concentration, poor pulp dispersion, low agitation speed, and low aeration rate. Finally, this paper provides insights into the future application prospects and research directions for WPCBs flotation technology.
