摘要：
A method of electrowinning a metal such as aluminum from e.g. a cryolite based melt containing alumina employs an anode having as its operative surface a protective coating which is maintained by the presence of constituents of the coating dissolved in the melt. The protective coating is preferably a fluorine-containing cerium oxycompound electro-deposited in-situ from cerium species dissolved in a fluoride-based melt.
