專利摘要(中)
一種含鎢合金的有價金屬元素回收方法，包含一設置步驟，及一電化學步驟。該設置步驟是將一陰極，及一作為陽極的含鎢合金浸入一電解溶液中，並使該電解溶液的pH值為中性、不大於2，或不小於10的其中一者。該電化學步驟是施加一電壓進行陽極處理，令該電壓通過該陽極時產生一不小於3W/cm2的功率密度，而可擊穿於陽極處理時形成於該陽極表面的金屬氧化物層，以令該陽極可持續的被氧化，並自該陽極釋出，得到一可溶解於該電解溶液的含鎢離子化合物，或一沉澱於該電解溶液的含鎢氧化物的其中至少一者。

專利摘要(英)
A method for separation of valuable elements from tungsten alloy includes a setting step, and an electrochemical step. In the setting step, a cathode and a tungsten-containing alloy which served as an anode are immersed in an electrolytic solution whose pH value is one of neutral, not greater than 2, or not less than 10. In the electrochemical step, an anodizing process is applied, and when the power density which generated due to a voltage passing through the anode is not less than 3W/cm2, the metal oxide layer which formed on the surface of the anode during the anodizing process would break down, so as to the anode is continuously oxidized and to obtain at least one of a tungsten-containing ionic compound dissolving in the electrolytic solution and a tungsten-containing oxide precipitated in the electrolytic solution.
