Method for producing electrolyte for vanadium batteries from oil sand waste

摘要

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.
