Copper Smelting Chemistry Tutorial

Calcine melts and its compounds react with the fluxes. Any copper (I) oxide present will be converted into copper (I) sulfide during the smelting process because copper has a higher affinity for sulfur than it does for oxygen. for example: Cu 2 O + FeS → Cu 2 S + FeO Impurities form a slag which floats on the surface and is easily removed.

Smelting - Wikipedia

Smelting involves more than just melting the metal out of its ore. Most ores are the chemical compound of the metal and other elements, such as oxygen (as an oxide), sulfur (as a sulfide), or carbon and oxygen together (as a carbonate). To extract the metal, workers must make these compounds undergo a chemical reaction.
