Abstract
Process and device for precipitating solid compounds from zinc metal baths. Partial amounts of the metal phase containing these compounds are exposed to an acceleration higher than gravity and dissociated into fractions containing heavier or lighter components. The molten mass depleted of solid compounds is returned to the metal bath. The device has a hollow rotary body for introduction into the molten mass and provided with a discharge opening for the depleted molten mass and a discharge opening for the liquid metal enriched with the solid compounds.
