Sulphuric dioxide gas is created in smelting copper process and is converted sulphuric acid which is used in some of the smelting processes or sold as a by-product. Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace.

CHARACTERIZATION OF GREEN AND CALCINED COKE …

electrolysis is caused by the oxidation of the anodes by air and C02, catalyzed by many different inorganic impurities present m the carbon anode materials. Iron catalyzes both O2 combustion and CO, gasification of carbon. Sulfur is inactive in and do not have a signilicant effect on both reactions.
