Why is zinc used in desilverisation of lead?
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.
How does the presence of zinc affect the extraction process of lead from its ore?
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.
