Making Vanadium | VanitecVanadium bearing oil based fuels are burnt in the boilers of electric power generating plant and vanadium is left in the fly ash and boiler slags. Vanadium in these ashes and slags is recovered by the same process as for vanadium coming from Flexicoke. Ashes and slag are also converted directly to ferrovanadium (40%V grade) via silicon reduction in an electric furnace.Recovery of vanadium and nickel in fly ash .Recovery of vanadium and nickel from an oil fly ash is studied in a two‐step leaching process, carried out under ambient pressure without calcination. In the leaching, nickel is dissolved with NH 4 Cl in the first step, followed by vanadium leaching with Na 2 CO 3 in the second step. Both leachants depress the dissolution of iron and ...
