Abstract: The present description relates to an anode arrangement for use in an electrolysis production of metals comprising an anode having a hollow body comprising a cavity, the body having at least one gas outlet connected in flow communication with the cavity. A gas inlet is connected in fluid flow communication with the cavity of the anode, the gas inlet being connectable to a source of hydrogen gas for feeding hydrogen gas into the cavity of the anode. The anode arrangement also comprises an electrical connector and a hydrogen chloride (HCl) recuperator surrounding at least a portion of the anode for recovering HCl gas released through the at least one gas outlet at an outer surface of the anode during electrolysis.

Abstract: An inert anode for Al electrolysis, made of Cu—Ni—Fe—O based materials, comprising Fe in a range between about 10 and 20% by weight, Cu in a range between about 60 and about 80% by weight, Ni in a range between about 20 and about 30% by weight, and oxygen in a range between about 1 and about 3% by weight, and a method for producing the anode, comprising mechanically alloying metallic elements; oxygen doping; and consolidation.
