METHOD FOR PRODUCING ELECTROLYTE FOR VANADIUM REDOX BATTERIES FROM OIL SANDS WASTE

摘要

A method for recovering Vanadium from a secondarysource such as fly ash. Leaching is involved using singleor combined acids such as hydrochloric and sulfuric in atemperature range of 20°C and 100°C. The leaching isperformed in sequential operations with recovery ofVanadium in the range of 92%. The recovered Vanadiumcan be formulated into an electrolyte for redox batteries
