  • Process for separating at least one first chemical element Efrom at least one second chemical element E, involving the use of a medium comprising a specific molten salt
    Patent number: 9677156
    Abstract: The invention pertains to a process for separating at least one first chemical element E1 from at least one second chemical element E2 coexisting in a mixture in the form of oxides, comprising the following steps: a) a step to solubilise a powder of one or more oxides of the said at least one first chemical element E1 and a powder of one or more oxides of the said at least one second chemical element E2 in a medium comprising at least one molten salt of formula MF—AlF3 wherein M is an alkaline element, after which there results after this step a mixture comprising the said molten salt, a fluoride of the said at least one first chemical elements E1 and a fluoride of the said at least one second chemical element E2; b) a step to contact the mixture resulting from step a) with a medium comprising a metal in the liquid state, the said metal being a reducing agent capable of predominantly reducing the said at least one first chemical element E1 relative to the said at least one second chemical element E2, after

  • Process for preparing an oxyhalogenide and/or oxide of actinide(s) and/or of lanthanide(s) from a medium comprising at least one molten salt
    Patent number: 9302918
    Abstract: The invention relates to a process for manufacturing an oxychloride or oxide of actinide(s) and/or of lanthanide(s) from a chloride of actinide(s) and/or of lanthanide(s) present in a medium comprising at least one molten salt of chloride type comprising a step of bringing said chloride of actinide(s) and/or lanthanide(s) present in said medium comprising at least one molten salt of chloride type into contact with a wet inert gas.
