FIELD: metallurgy.
SUBSTANCE: electrolyser contains heated cathode and anode cavities separated by vertical porous membranes impregnated by the electrolyte, that are separated with creation of the intermediate cavity between them, and are fixed by the gaskets , near cathode porous membrane is made out of carbon-graphite fabric, and near anode membrane is made out of dielectric quartz fabric, sprayed by liquid anode alloy using the circulating pump, in which line of the metal supply has valve for switching from the circulation line to the unloading line.
EFFECT: high degree of removal of the admixtures, reduced output of bismuth on the cathode with admixtures.
