Smelting is a metallurgy technique to extract base metals from their ores with the help of heat and a chemical reducing agent.
The process of obtaining a metal either as an element or as a simple compound from its ore by heating beyond the melting point in the presence of oxidising agents such as air and coke is known as smelting. Copper is the first metal to be smelted followed by tin, lead and silver. To achieve high temperatures required for smelting, furnaces with forced air drafts are used. In modern copper smelting, a reverberatory furnace is used.
