    The proposed treatment for the recovery of vanadium from oil fly ash is complex, requiring a series of processing steps that make vanadium valorization economically debatable. However, considering vanadium as a by-product of the washing of oil fly ash, its recovery may contribute, at least, to reduce the net cost of the treatment by the production of valorizable sub-products.
