fine fly ash with a long atmospheric residence time. Vanadium concentrates on the surface of particulate matter from coal combustion. The concentration of vanadium in fly ash from residual fuel-oil burning averages around 8% (range 2-18%), representing 56% (39-74%) of the vanadium concentration in fuel.

Abstract In Jordan, large amounts of fly ash (FA) are produced as a result of burning heavy fuel in power plants. Extraction of metals from FA is an important industrial/environmental issue to assess metals' mobility and applications. Large amounts of metals (V, Ni, Fe, Ca, Mg, Na, and K) were easily leached from FA under acidic, basic, and neutral conditions and this makes disposal of this

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

01-01-2007· The proposed treatment for the recovery of vanadium from oil fly ash is complex, requiring a series of processing steps that make vanadium valorization economically debatable. However, considering vanadium as a by-product of the washing of oil fly ash, its recovery may contribute, at least, to reduce the net cost of the treatment by the production of valorizable sub-products.

01-09-2011· Highlights Large amounts of fly ash are produced as a result of burning diesel fuel in power stations. Ni is selectively eluted from the FA using NH 3 solution and was precipitated as NiS. V is extracted from Ni-free-FA by Na 2 CO 3 solution and precipitated by NH 4 Cl. The proposed method herein showed a high recovery (97%) for both metals.
