Beschreibung
Zusammenfassung:	A method for the recovery of vanadium from a vanadium containing feed stream, the method comprising the steps of: subjecting the vanadium feed stream to a leach step, the leach step comprising contacting the vanadium feed stream with an alkaline carbonate leach solution to form a leach slurry comprising a pregnant leach solution containing vanadium and a solid residue; passing the leach slurry to a solid/liquid separation step to produce a pregnant leach solution containing vanadium; and recovering a vanadium product from the pregnant leach solution.
