摘　　要：废旧电路板是一种高价值的危险废物,因其含有的金属组分与非金属组分之间的天然疏水性差异较大,采用浮选法从中回收有价组分的方法受到了广泛关注。综述了在废旧电路板浮选回收中浮选药剂、强化浮选、浮选影响因素及浮选动力学等方面的研究进展,指出与传统矿石浮选相比,废旧电路板浮选具有给矿粒度粗、矿浆质量浓度低、矿浆分散性差、搅拌速度小、充气量小等特点。最后,展望了废旧电路板浮选技术未来的应用前景及研究方向。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.
