Smelting Oxidation Desulfurization Of Copper Slags

Copper Smelting Chemistry Tutorial

Copper Smelting Chemistry Tutorial

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. One of the reactions to remove iron impurities is shown below:
