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.
