What is Smelting?
Smelting is a pyrometallurgical process used to extract metals from their ores by heating the ore with a reducing agent (usually carbon/coke) and a flux at high temperatures in a furnace. The reducing agent removes oxygen from metal oxide ores, and the flux reacts with impurities to form slag. The molten metal sinks to the bottom and is separated from the slag.
