A method of extracting valuable metals from a petroleum fuel ash sodium roasting

The present invention discloses a method of extracting seed oil from fuel ash sodium roasting valuable metals, with sodium first roasting vanadium separation of nickel, vanadium converted into a soluble sodium vanadate, sodium vanadate solution was washed with water to obtain leaching, the purified Shen high-purity ammonium metavanadate, vanadium, nickel, nickel in the form of ice remained in the leaching residue can be used to produce nickel products progress. Advantage of this process is the separation of vanadium and nickel, and vanadium products obtained high purity nickel matte.
