FIELD: electrochemistry.
SUBSTANCE: invention relates to extraction of indium by electrolysis. Disclosed is an electrolytic cell for extraction of indium from melt discharge of condensate of refining crude tin from vacuum furnace. Electrolytic cell comprises heated condensate tank of a vacuum furnace, used as anode bath, immersed therein a cathode cell with perforated walls, lined with a diaphragm made of quartz cloth, barometric pipe, cathode current lead and a cup fixed thereon and placed inside cathode cell. Cell additionally comprises cathode plates. Cathodic cell walls are composed of two perforated strips coiled into a spiral to form a gap between them for electrolyte and immersion therein of cathode plates. Wall of cell on one side is fixed on inner side of condensate tank, and on other on barometric pipe. Cathode plates are made of zinc alloy.
EFFECT: higher extraction of indium from condensate.
