Abstract: Ammonium sulfate slurry produced by desulfurizaion d iron and sateel sintering flue gas byammonia method has the characteristics d high-speed enrichment and difficult removal. 'This paper sum-marizes the traditional fluoride remnoval technclogies for fluoride-containing wastewater and fluoride remov-al methods in desulfurization liquid ,and the technical status of each fluoride remowval method is deeplyanalyzed.'The aim of this paper is to explore the feasibility of various fluoride removal methods that ap-plied to the fluoride removal of ammonium sulfate slurry for ammmonia desulfurization of sintering flue gas.'The research emphases of fluoride remwval by anmonium sulfate slurry in the future,which provides areference for the method of sintering flue gas.

Key words: sinteringfluegas, ammonia-routedesulfurization, ammonium sulfate, fluorideremovalmethods, feasibility
