Copper production process with diagram

Jan 01, 2014 Ellingham Diagram for Sulfides. Because pyrometallurgical processes take place at high temperatures in which chemical reactions are fast, most steps in the overall process tend to proceed near equilibrium conditions. Therefore, the important principles involved in pyrometallurgical production of copper are related to the free energy/temperature
