Method for extracting pure ammonium rhenate from rhenium-contained extracting liquid

The invention discloses a method for extracting pure ammonium rhenate from rhenium-contained extracting liquid, belongs to the field of ammonium rhenate purification in wet metallurgy, and solves theproblems of complex operation in preparation of ammonium rhenate, lower recovery rate and higher cost in the prior art. The method comprises the steps of reverse extraction by hydrochloric acid, introduction of chlorine, generation of precipitations by adding ammonium chloride, washing of the precipitations through ammonium-contained hydrochloric acid, washing by ethanol solution after filtrationof the precipitations, drying of powder after washing of chlorine ions, and obtaining of high-purity ammonium rhenate powder. The method is simple in process, mild in reaction, simple in operation, low in cost, high in yield and easy to realize scale production; and meanwhile, the product is powder with high purity to achieve subsequent preparation of high-purity rhenium powder. 本发明公开了种从含铼萃取液中提取高纯铼酸铵的方法，属于湿法冶金中铼酸铵的提纯领域，解决现
