Abstract
The voltage drops across the elements of a three-chamber electrolytic cell are measured during the synthesis of perrhenic acid from potassium perrhenate, and the main contribution to the total bath voltage is shown to be made by the central chamber solution because of the low solubility of potassium perrhenate. The direct electrodialysis recovery of rhenium from the alkaline electrolytes formed during the anodic dissolution of tungsten–rhenium alloys is found to be unreasonable because of a rapid decrease in the process rate and high electric power consumption. The cleaning of tungsten–rhenium electrolytes from tungsten for the subsequent recovery of rhenium from a solution in the form of perrhenic acid is tested. The application of this technological sequence is shown to decrease the electric power consumed for electrodialysis fivefold and to decrease the rhenium losses die to the elimination of the stage of precipitation of potassium perrhenate. A fundamental technological scheme of the process is proposed.
