Abstract

Procedure to extract a metal from an electrolyte; characterized by comprising contacting the electrolyte with an anode and a cathode and passing an electric current between the anode and the cathode, the cathode having a surface of titanium or titanium alloy which has been treated by introduction into an alkaline aqueous solution substantially free of fluoride and an organic complexing agent for titanium selected from the group: an ether, an alcohol, an aldehyde, a ketone, an amine, a nitrile, a sugar, a salt of an organic acid or any of its derivatives, being such the arrangement that a distorted anatase titanium oxide film is formed which continually thickens on the titanium or titanium alloy surface.
