FIELD: metallurgy.
SUBSTANCE: proposed method washing off of regeneration cryolite pulp in condensate formed in heating of cryolite in pulping reactor. Duration of washing-off makes 30-60 minutes, temperature of condensate used for purifying if regeneration cryolite of sulfur compounds makes 50-80°C, volume ratio of used condensate to purifying pump makes (5÷8):1.
EFFECT: reduced costs, high quality.
