VANADIUM COMPOUND DISSOLUTION PROCESSES

摘要

Processes for dissolving and reducing a reducible vanadium compound disposed in, but not wholly dissolved in, an aqueous electrolyte by utilizing an electrochemical cell and/or a chemical reductant are disclosed. In one process of the invention a reducible vanadium compound is disposed in, but not wholly dissolved in, an aqueous electrolyte and a chemical reductant is added to the electrolyte to dissolve and reduce the compound in the electrolyte. In another process of the invention a reducible vanadium compound is disposed in, but not wholly dissolved in, an aqueous electrolyte by utilizing an electrochemical cell which aqueous electrolyte is in electrical contact with a positive electrode and a negative electrode and electrical energy is provided from an external circuit to the positive and negative electrodes to dissolve and reduce at least a part of the compound in the electrolyte.
