FLUORINE EXTRACTION SYSTEMS AND METHODS Russian patent published in 2014 - IPC C01B7/20 C01G43/01 

FIELD: chemistry.

SUBSTANCE: method of extracting fluorine involves feeding a mixture containing uranium fluoride and an oxidant into a reaction vessel with a solid base and an opening facing the base, heating said mixture in the reaction vessel and forming at least one uranium oxide and a non-radioactive gaseous product from the heated mixture. Thickness of the layer of the mixture in the reaction vessel is controlled to achieve the required reaction output and/or required rate of reaction of producing the non-radioactive gaseous product. The mixture used contains uranium tetrafluoride UF₄ and a reactant for extracting fluorine, which is selected from a group comprising germanium oxide GeO, germanium dioxide GeO₂, silicon Si, boron trioxide B₂O₃ and silicon dioxide SiO₂.

EFFECT: invention increases output of fluorine.
