History of Lead Smelting. The process of creating lead can be traced back to 6500 B.C. Lead was created by dumping lead ore inside a furnace along with charcoal. However, it seems as though the lead was not used that often in the ancient past. The main problem was that it is too soft to be used to create a structure or forge weapons.

The matte, about 45 to 55 percent copper and the remainder iron silicate slag, is formed in a very fast, almost instantaneous reaction; hence the name "flash smelting.". The matte sinks through the lighter slag layer and flows down the. inclined crucible. Conversion to copper proceeds in a zone around position two.

Smelting is a process in which the base metal is extracted from the ore by applying heat to it. It is one kind of extractive metallurgy. It is used for the extraction of many metals like copper, aluminium, iron, silver, lead and many other base metals from their respective ores. For the decomposition of the ores, smelting uses heat and chemical ...
