Abstract: Combined with the basic characteristics of circular economy，three important links that followed by the fluorine resources recycling were analyzed from the perspective of the fluorine recycling.The recycling of fluorine-contained by-product from electrolytic aluminum industry and photovoltaic industry，as well as the its recycling technology′s research and development was mainly introduced.Sources of fluorine-contained waste，quality indexes，process methods，and optimization of process flow etc.were described in detail.In addition，the feasibility of industrialization was proved from the product quality contrast，industrial equipment selection，and economic benefit etc..The environmental and social benefits generated from the application and extension were also pointed out.  

Key words: circular economy, fluorine resources, PV, electrolytic aluminum, cryolite
