The pyrometallurgical production of copper from sulfide concentrates is a journey involving the gradual oxidation of copper concentrates in sequential steps. These steps are smelting, converting, and refining. The overall copper making process can be explained by using the copper–oxygen–sulfur predominance diagrams.
