Zinc: 7.133 at 25°C
Lead: 11.34 at 16°C
No, zinc does not contain lead. Zinc and lead are two different elements with distinct chemical properties.
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.
The melting point of zinc is 419.5°C, while the melting point of lead is 327.5°C.
Yes, a reaction will take place. The zinc metal will displace the lead in the lead(II) sulfate solution, forming zinc sulfate and lead metal. This is because zinc is higher in the reactivity series than lead.
The presence of zinc can affect the extraction process of lead from its ore by forming a zinc-lead alloy, which has a lower melting point than pure lead. This allows for easier separation of lead from the ore during the smelting process.
No. The specific gravity of lead is 11.35 and the specific gravity of diamond is 3.5, which is above average, but not heavier than lead.

State of Charge
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.
Specific gravity of the electrolyte in the lead acid cell or battery (assuming that the battery is not of the sealed type) is often used as a measure of its STATE OF CHARGE. Sure we can do the same with a multimeter but the above method is more accurate.
Rate of Discharge
An object with a specific gravity greater than 1 will not float in water. Since water has a specific gravity of 1, any material with a specific gravity exceeding this value will sink. For example, metals like lead and gold have specific gravities significantly higher than 1, causing them to sink when placed in water.
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.
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.
