FIELD: metallurgy.
SUBSTANCE: electrolytic cell comprises heated cathode and anode baths separated by porous diaphragms impregnated with electrolyte. The cylinder of the cathode bath is arranged as perforated, and a diaphragm from quartz fabric is fixed on it with a yoke above the perforation level. The cathode bath is vertically submerged into the melt of the initial alloy of the anode bath equipped with a mixer. Inside the cathode bath a cup is installed onto the bottom from the diaphragm and fixed on the cathode current conductor. At the same time the cathode bath cylinder is submerged into the alloy melt in the anode bath at the perforation height. The cup fixed on the cathode current conductor is installed below the cylinder perforation level. On the cylinder of the cathode bath there are two layers of the diaphragm fixed from quartz fabric.
EFFECT: higher stability of operation, higher extent of indium extraction with higher extent of separation from electric positive metals.
