| Abstract: | Considering fluorine resorce, the enviroment being smelting technology of fluorinate carbonaceous cerium is put forward in this article. The fluorine recovery is 70% in this new technology. Some process steps are decreased, such as reduction of Ce(IV), elimination of Fe and Th. H 2SO 4 can be used repeatedly. The percent recovery of CeO 2 can be raised by 10%. This techhology can reduce the pollution burden in quantity and make full use of the resorce. |
