Vanadium recovery from oil fly ash by leaching ...

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 irri-gation water are 200 ppb and 10 mg L 1, respectively (Juste et al., 1995). However, regulations imposed in many

Extraction and separation of vanadium and nickel from

01/09/2011  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 material an important environmental issue.

Value in Waste: Fly Ash Reuse and Recovery Opportunities

One of the primary targets for recovery from fly ash has been alumina; most fly ash contains between 25 – 30% aluminum oxide (Al 2 O 3)¹. Some sources of fly ash in China have been shown to contain as much as 45% alumina. ² In addition to its use in producing aluminum metal, alumina is used throughout a host of industries as a catalyst, pigment, abrasive, and a long list of other materials.
