THERMAL REDUCTION PROCESS FOR THE RECOVERY OF REFRACTORY METAL OXIDES AND THE PRODUCTION OF VANADIUM-RICH IRON ALLOYS FROM MINING RESIDUES OR METALLURGICAL WASTES BY-PRODUCED DURING THE BENEFICIATION AND UPGRADING OF TITANIA SLAGS

A process for producing vanadium-rich iron alloys and refractory metal oxides is described. The process comprises submitting mining residues or metallurgical wastes to at least one reductive thermal treatment to produce a reduced material; submitting the reduced material to at least one magnetic sep...

Beschreibung
Zusammenfassung:	A process for producing vanadium-rich iron alloys and refractory metal oxides is described. The process comprises submitting mining residues or metallurgical wastes to at least one reductive thermal treatment to produce a reduced material; submitting the reduced material to at least one magnetic separation step to produce magnetic fractions of differing magnetic susceptibilities; and recovering the magnetic fractions.
