AVL To Collaborate With UK Company GSA Environmental On

Vanadium and other metals, such as nickel, are contained in a variety of wastes including fly ash which is generated from crude oil. This material is currently disposed of in landfill sites around the world. Extracting the saleable material from this waste will therefore have a positive economic and environmental impact.

Making Vanadium Vanitec

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 removed from the organic salts with soda ash. Vanadium polyvanadate is precipitated by the addition ammonium sulphate.

About Vanadium Bushveld Minerals

Secondary production of vanadium is the recovery of material from fly ash, petroleum residues, alumina slag, and from the recycling of spent catalysts used in some crude oil refining. It accounted for 11 % of global supply in 2019.

Aug 26, 2019 The non-vanadium metals, such as iron, titanium, and nickel, are then sold at market prices which subsidizes the vanadium extraction. There is a lot of oily fly ash and coal waste to be had.

Recovery of vanadium and nickel in fly ash from heavy oil

Recovery of vanadium and nickel from an oil fly ash is studied in a two‐step leaching process, carried out under ambient pressure without calcination. In the leaching, nickel is dissolved with NH 4 Cl in the first step, followed by vanadium leaching with Na 2 CO 3 in the second step.
