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 countries require companies to process the waste

Extraction and separation of vanadium and nickel from fly

01/09/2011 Extraction and separation of vanadium (V) and nickel (Ni) from FA is achieved using Akita's procedure with some modifications. In the first step, Ni is selectively eluted from FA using NH 4 OH solution and then precipitated using Na 2 S. The Ni/V ratio in final precipitate was 27.

Extraction and separation of vanadium and nickel from fly

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

30/04/2015 There is a common belief that all fly ash produced in Europe is being utilised in construction already, but this predominately applies to Class C ashes, not the non-cementitious Class F ashes, and data suggests that even now over 40% of the total fly ash is under-utilised (low value fill material) or un-utilised. In addition, some of the leading players in metal recovery are developing routes
