Vapor phase extraction of vanadium, nickel and magnesium from a fly ash of Orimulsion®, a new fuel, has been investigated using high-temperature chlorination with N 2 –Cl 2 or air–Cl 2 gas mixture. The use of N 2 –Cl 2 gas was suited for a selective chlorination of metal components. Vanadium and iron were extracted at 400 and 500 °C, respectively, as …

The uranium and vanadium are separated from the liquid by solvent extraction followed by a liquid-liquid ion exchange process which separates the uranium leaving the vanadium in the acid solution. This is subsequently oxidised and …

In this study, the Taguchi design method was employed to determine the optimum experimental parameters in extraction of vanadium by NaOH leaching of oil-fired fly. Prior to designed experiments, the raw precipitates were mechanicallly milled using a high-energy planetary ball mill. Experimental parameters were investigated as follows: mechanical milling …

If electrostatically precipitated fly ash was leached in a solution of 0.25 N ammonia water and 2 N ammonium sulfate, it would yield an extraction of 60% nickel and 8% vanadium—leading to a ...

Extraction and separation of vanadium and nickel from fly ash Extraction of metals from FA is an important industrial/environmental issue …

Increasing production and disposal of coal fly ash (CFA) is a matter of serious environment concern. However, CFA contains various beneficial metals and mineral matters whose demand is increasing in the industrialized world, while natural supplies are diminishing. Therefore, recovery of these potential resources from CFA can be an alternative way to save …

The production of refinery grade oil from the Alberta tar sands deposits as currently practiced by Suncor (formally Great Canadian Oil Sands Ltd.—GCOS) generates a substantial amount of petroleum coke fly ash which contains appreciable amounts of valuable metals such as vanadium, nickel and titanium. Although the recovery of vanadium from petroleum ash is a well …

Hydrometallurgical processes for the extraction of vanadium have been proposed in the last decade as a lower cost alternative in replacement of the conventional processes but they fail to produce a high quality iron co-product. ...

Vanadium and nickel have many and continuously increasing industrial applications (Vitolo et al., 2001;Tsygankova et al., 2011). Among the compounds of vanadium in …

The extraction of vanadium from fly ash of stone coal combustion in China was studied by alkaline leaching. The fly ash was characterized by a relatively high …

Under these conditions, the extraction of vanadium can reaches 98%. Keywords vanadium, heavy fuel, fly ash, leaching, extraction 1. Introduction The power generation station that uses heavy oil produces a solid residue called fly ash [1]. Fly ash generated during oil combustion. Fly ash is rich in Ni, V, Fe, Mo, Mg, Na and C and among these metals

In the world, large amounts of fly ash(FA) are produced as a result of burning heavy oil in power plants every year. Extraction of metals from FA is an important industrial/environmental issue to assess metal's mobility and applications. Large...

Secondary production is the recovery of vanadium from fly ash, petroleum residues, alumina slag, and from the recycling of spent catalysts used in crude oil refining. It accounted for approximately 10% of global supply in 2020. In 2020, global vanadium production increased to 116,128 mtV from 109,643 mtV in 2019.

Key words: Flyash, DC arc furnace, Pre-treatment, Smelting, Vanadium, Nickel, Extraction, Recovery. ABSTRACT Flyash is a powdery residue generated by the power stations that use heavy oil as the source of fuel. The ash poses a threat to the environment due to the presence of certain heavy elements such as chromium.

The fly ash produced during the upgrading of the Alberta oil sands contains between 2.0 and 3.5 wt% vanadium, and represents a significant vanadium resource (3.6 million kilograms per year or 3.5% of total world vanadium production). Research was performed to move vanadium recovery from the oil sands fly ash towards commercialization.
