FIELD: metallurgy, in particular, refining of low-melting-point metals in fused electrolyte, having a pool cathode, anode and bipolar electrode parallel arranged in the vertical. SUBSTANCE: cathode bipolar electrode, and anode are arranged in succession from top to bottom, the cathode is positioned on a porous dielectric engageable with the surface of the bipolar electrode metal, and the porous dielectric of the bipolar electrode is engageable with the anode surface. EFFECT: enhanced efficiency. 1 dwg, 1 tbl
