  • Process for producing vanadyl/vanadous sulphate
    Patent number: 6764663
    Abstract: A process for preparing a reconstituted vanadyl sulphate/vanadous sulphate solution for use as an electrolyte in a vanadium redox battery is disclosed. The process includes preparing a starting material including a vanadyl sulphate/vanadous sulphate solution, evaporating the starting material by applying heat to form vanadyl sulphate/vanadous sulphate crystals, and re-dissolving the vanadyl sulphate/vanadous sulphate crystals with a volume of de-ionized water to form a reconstituted vanadyl sulphate/vanadous sulphate solution having substantially the same chemical composition at the starting material. A process for preparing a vanadyl sulphate/vanadous sulphate starting material from a vanadium bearing ore material, particularly a titaniferous magnetite ore material is also disclosed.
