ABSTRACT:
Improved cathode starting blanks for metal electrowinning are produced when valve metal sheets are coated with a thin layer containing either silver or silver-valve metal alloys, particularly silver-yttrium alloys, and/or oxides thereof. Said blanks are used in the electro-deposition of strippable metal coatings such as in electrowinning and/or electro-refining of metals. The improved method of recovering a metal from an electrolyte using these cathode blanks and the electrowinning cells containing said cathode blanks are also a part of the invention.
