How can zinc be separated from lead in the condenser?
In the blast furnace a mixed lead/zinc sinter is added and the lead bullion is tapped conventionally from the bottom of the furnace while metallic zinc vapour is distilled off and captured/condensed by a spray of molten lead droplets. A solution of zinc and lead leaving the condenser, when cooled this cool zinc can be floated off, while the lead is recirculated to the collector. Zinc being less dense can be continuously removed from the top layers.
