How lead is made - material, used, processing, product ...

Lead is used to make bearings and solder, and it is important in rubber production and oil refining. Lead production dates back at least 8,000 years. Lead was used in Egypt as early as 5,000 B.C., and in the time of the Pharaohs it was used in pottery glazes and as solder. It was also cast into ornamental objects.

Lead (Metal) - an overview | ScienceDirect Topics

Cupellation is the refining process that separates noble metals from impure metals/alloys treated under very high temperatures and controlled operations. Lead melts at 327°C, lead oxide at 888°C, silver at 960°C. The impure lead metal/alloy is melted at a high temperature of 960–1000°C in an oxidizing environment.
