CA2962794A1 - Method for producing electrolyte for ...

A method for recovering Vanadium from a secondary source such as fly ash. Leaching is involved using single or combined acids such as hydrochloric and sulfuric in a temperature range of 20 C and 100 C. The leaching is performed in sequential operations with recovery of Vanadium in the range of 92%. The recovered Vanadium can be formulated into an electrolyte for redox batteries

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.
