· Smelting is the method of extracting a metal, either as an element or as a simple compound, from its ore by heating it above its melting point, usually in the presence of oxidizing agents such as air or reducing agents such as coke.

Smelting is a process of extracting pure metals from their ores through heating and melting. It is an essential step in producing usable metals from raw ores extracted from mines. The end product of smelting is molten metal, which can then be refined into pure metal for use in making various products. In smelting, ore is heated with chemical
