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.
A good method is distillation.
A good method of separation in this case is distillation.
You could submerge the galvanized iron in HCl, which would then dissolve the zinc, at which point you could weigh the iron again to determine the mass of zinc that was removed.
Zinc is more reactive than Lead nitrate (See Displacement Series). Therefore, Zinc will displace lead in lead nitrate: Zn + Pb(NO3)2 -> Zn(NO3)2 + Pb
Zinc was often confused with lead and tin due to their similar appearances. However, zinc has a higher melting point than lead and tin, and it does not oxidize easily like lead and tin.

A good method of separation in this case is distillation.
Lead metal and zinc metal can be separated in a furnace using a process called fractional distillation. The furnace is heated to a temperature above the boiling point of zinc but below the boiling point of lead. The zinc will vaporize and can be collected, leaving the lead behind in the furnace.

No, zinc does not contain lead. Zinc and lead are two different elements with distinct chemical properties.
Zinc*
Zinc is used in the desilverization of lead because zinc has a higher affinity for silver than lead does. When zinc is added to molten lead containing silver, zinc combines with silver to form a zinc-silver alloy, which then floats to the surface for easy removal, leaving behind lead that is desilverized.
Molten argentiferrous lead is jmixed with zinc being lighter forms upper layer and silver being soluble in zinc goes into the molten zinc on cooling zing the upper layer gets solidified and separated by the help of big perforated spoons the prociss is repeated several times till lead so completely free from silver
Zinc is always found in combination with lead and silver. The largest lead-zinc-silver mine in Australia is Mount Isa, producing about 4.5 million tonnes silver-lead-zinc ore per annum with concentrations of: 154g/t silver 5.4% lead 6.5% zinc
The melting point of zinc is 419.5°C, while the melting point of lead is 327.5°C.
This category covers establishments primarily engaged in mining, milling, or other wise preparing lead ores, zinc ores, or lead-zinc ores
