Recovery of vanadium and nickel from Athabasca tar sands fly ash
Low percentages of vanadium, nickel and iron are associated with the bitumen fraction of tar sands. Compounds of these elements are concentrated into the fly ash produced when the petroleum coke fraction of this bitumen is burned. It appears that these sands also represent a resource for vanadium and, to a lesser degree, for nickel provided that suitable extraction
