Vanadium Recovery from Oil Fly Ash by Carbon

Vanadium recovery from oil fly ash by leaching ...

The dispersion of fine particles of oil fly ash and the high solubility of vanadium may cause a dispersion of vanadium in water and soil. Due to the low toxicity of vanadium compared to other heavy metals, the accepted levels for vanadium in water supplies and irrigation water are 200 ppb and 10 mg L −1 , respectively ( Juste et al., 1995 ).

2013-10-10  values (up to 400 μg/g) in areas polluted by fly ash (4). The concentration of vanadium in water is largely dependent on geographical location and ranges from 0.2 to more than 100 μg/litre in freshwater (2), and from 0.2 to 29 μg/litre in seawater (3). The ocean floor is the main long-term sink of vanadium in the global circulation (4).

RECOVERY OF VANADIUM AND NICKEL FROM

2012-2-7  flyash followed by a combustion step to remove carbon and sulphur. The treated ash is then reduced by smelting in a DC arc furnace, using ferrosilicon or aluminium, to produce a vanadium alloy and a disposable slag. A testwork program was designed to demonstrate the application of this flowsheet to the ash. The test program covered 60 kVA induction
