Species wet processing of fuel ash extraction of valuable metals

The present invention discloses a kind of fuel ash wet processing method of extracting valuable metals, the main process are: fuel ash into the water, pH was adjusted to 7-9 by adding aqueous ammonia, an oxidizing agent is added to the pentavalent vanadium oxide, vanadium into the solid phase of nickel remaining in the liquid phase, separated by filtration, the filtrate was mentioned nickel, a base and processing the progress of ion-exchanged ammonium removal, emissions; cake with hot water was dissolved vanadium, vanadium precipitation was filtered to obtain crystals of ammonium metavanadate. This process is a kind of green economy vanadium, nickel extraction process.
