Abstract

Process for the enrichment and separation of the niobium and tantalum elements from their pentahalogenuric mixtures, characterized in that they react with each other mixtures of pentahalides, especially mixtures of niobium pentachloride and tantalum pentachloride, and by separating them from a fraction enriched in niobium the double salts rich in tantalum that have formed.
