PCT No. PCT/EP84/00010 Sec. 371 Date Aug. 20, 1984 Sec. 102(e) Date Aug. 20, 1984 PCT Filed Jan. 13, 1984 PCT Pub. No. WO84/02724 PCT Pub. Date Jul. 19, 1984.A method of electrowinning a metal such as aluminum from e.g. a cryolite based melt containing alumina employs an enode 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. |
