Smelting, process by which a metal is obtained, either as the element or as a simple compound, from its ore by heating beyond the melting point, ordinarily in the presence of oxidizing agents, such as air, or reducing agents, such as coke. The first metal to be smelted in the ancient Middle East was probably copper by 5000 bce , followed by.

Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide silica, calcium carbonate CaCO 3 and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulfide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.
