Abstract (en)
[origin: WO2007145526A1] This invention describes a method of producing a metal, M<SUB>1</SUB>, in an electrolytic cell consisting of a molten electrolyte, M<SUB>z</SUB>Y - M<SUB>z</SUB>O, at least one anode and at least one cathode, characterised in that the passage of current between said anode(s) and cathode(s) through said electrolyte, produces a metal, M<SUB>1</SUB>, from a raw material, M<SUB>1</SUB>X, containing a non-metallic species, X, under conditions such that the potential at the cathode causes the reduction of the M<SUB>z</SUB> cation and the formation of M<SUB>2</SUB> at activities less than one, and the potential at the cathode is insufficient to cause formation of M<SUB>z</SUB> metal as a discrete solid or liquid phase, and the M<SUB>z</SUB> so produced reduces the raw material, M<SUB>1</SUB>X, at the cathode, to M<SUB>1</SUB>.
