| Abstract: | The extent of purifying and removing impurities in oxidation refining is obtained after a detailed data calculation being made to the five basic chemical reactions incurred in the process and thermodynamic analysis being made based on the free enthalpy-temperature diagram.A reasonable composition of anode copper generated after it being processed under oxidation refining is obtained.By taking actual practice into consideration, the extent of removing various impurities in the crude copper during the fire refining process in factory production can be calculated out. |

| Keywords: | fire refining thermodynamics crude copper impurity oxidation |
