Abstract

Process for the separation of niobium and tantalum, characterized in that materials containing niobium and tantalum are transformed into oxidized form, particularly minerals containing niobium and tantalum which have been subsequently treated for the purpose of enrichment, or mixtures of oxides of these two metals, with chlorine gas and a reducer in a mixture of chlorination products that contain preponderant or exclusively niobium such as oxychloride and tantalum as pentachloride and because this mixture is subjected to fractional condensation, or it is dissociated by sublimation into fractions.
