| titleOfInvention | A kind of method for recovering vanadium nickel aluminium from sulfuric acid ripening leaching solution |
| abstract | The invention provides a method for recovering vanadium-nickel-aluminum from sulfuric acid aging leaching solution. The method adopts a cascade recovery process of vanadium oxide precipitation-vanadium refining-hydrolysis precipitation aluminum-aluminum-iron separation-carbonate precipitation nickel, and the method of the invention operates Simple, short process, low energy consumption, low equipment requirements, and pollution-free additives, the produced waste liquid can be evaporated and crystallized and returned to use, and the solid slag can be sold as an intermediate product. The results show that the invention can realize the efficient recovery and separation of vanadium, nickel, aluminum and iron in the aging leaching solution, obtain high-purity ammonium metavanadate, the recovery rate of vanadium can reach more than 95%, and the recovery rate of nickel and aluminum can reach more than 90%. It has good environmental and economic benefits and is suitable for industrial applications. |
