| titleOfInvention | Method for separating rhenium and arsenic, and method for purifying rhenium |
| abstract | The purpose is to stably remove arsenic, which is an impurity, from a raw material containing rhenium and arsenic, and to stably obtain low-arsenic grade rhenium by reducing the amount of arsenic circulating in the rhenium purification process. . In the present invention, the raw material containing rhenium and arsenic is oxidized and leached, separated into a leachate containing perrhenic acid, arsenic acid, and arsenous acid and an leaching residue containing arsenate, and rhenium is purified from the leachate. A method for separating rhenium and arsenic in a process, wherein alkali is added to a leachate to obtain a arsenic-containing precipitate and a rhenium-containing solution, and the rhenium is separated from the obtained rhenium-containing solution. In an arsenic-containing solution obtained by adding alkali to one or both of the obtained arsenic-containing precipitate and leaching residue containing arsenate to obtain an arsenic-containing solution and a hydroxide precipitate Of arsenic as a precipitate. |
