PROBLEM TO BE SOLVED: To provide a method for efficiently separating and recovering tungsten and other valuable materials from valuable materials including tungsten.SOLUTION: In a method for recovering valuable materials including tungsten, a raw material mixture containing valuable materials including tungsten is electrolyzed using an electrolyte containing alcohol amine, whereby the tungsten is dissolved in the electrolyte, a part of the valuable materials is electrodeposited on a cathode used for the electrolysis, and the valuable materials other than the valuable materials electrodeposited on the cathode are formed as a residue in the electrolyte to separate and recover these components respectively.SELECTED DRAWING: Figure 1 |
