摘要： Ferroniobium, ferrotantalum and ferrovanadium alloys are hydrogenated to facilitate crushing then nitrided, and then acid-leached to produce a soluble iron nitride leachate and a niobium, tantalum or vanadium nitride residue which residue can be denitrided to yield the metal which can be recovered by melting.
