  • Copper Smelting Chemistry Tutorial

    Calcine is heated to over 1200 o C with fluxes such as silica (SiO 2) and limestone (CaCO 3). 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 ...
