| Abstract: | Causticizing mud was used as a roasting additive of sodium chloride for extraction of vanadium pentoxide from stone coal. The raw feed after roasting was leached by water, and then by ammonium bicarbonate and introduced carbon dioxide under high pressure. The leaching solution was purified by ion exchange, and then ammonium metavanadate was precipitated. A qualified product V 2O 5 was obtained by calcining ammonium metavanadate. |
