Definitions
- the step of subjecting the feed stream to a leach step is conducted at atmospheric pressure.
- the leach slurry 44 is directed to a solid liquid separation step to separate any solids from the pregnant leach solution.
- the slurry 44 is directed to a counter current decantation (CCD) circuit 46.
- CCD counter current decantation
- the slurry 44 is washed in a series of thickeners until the majority of the dissolved metals are removed.
- the slurry 44 is directed into the first thickener and the wash solution is directed to the final thickener.
- the underflow and overflow flow counter current to one another.
- a flocculent 48 may be added to one or more of the thickeners to aid in the separation process.
- the overflow 49 from the first thickener is directed to further processing to recover metals.
- the slurry may be directed to a filtration step, using a belt filter or other filtration devices.
- the filtration step would preferably also include a wash step.
- the pH is increased to between 3 and 4.5. In one embodiment of the present invention, the pH is increased to between 3.5 and 4.5. In one embodiment of the present invention, the pH is increased to between 4 and 4.5.

L'invention concerne également un procédé de récupération de vanadium à partir d'un flux d'alimentation contenant du vanadium, le procédé comprenant les étapes consistant : à soumettre le flux d'alimentation contenant du vanadium à une étape de lixiviation acide pour former une bouillie comprenant une solution de lixiviation enrichie qui comprend du vanadium dissous et un résidu solide ; à faire passer le produit de l'étape de lixiviation à une étape de séparation solide/liquide pour produire une solution de lixiviation enrichie qui comprend du vanadium dissous ; à mettre en contact la solution de lixiviation enrichie avec un agent réducteur pour réduire une ou plusieurs espèces dans la solution de lixiviation enrichie ; à faire passer la solution de lixiviation enrichie à une étape de précipitation dans laquelle le pH de la solution est augmenté pour précipiter un produit de vanadium ; et à récupérer le produit de vanadium à partir de la solution.
