The decreasing quality of the input materials in copper recycling leads to a higher content of impurities in the anode copper. An improvement of the pyrometallurgical refining process is therefore necessary to produce high quality anodes for the copper refining electrolysis. The behavior of the most important accompanying elements (e.g. nickel, tin, lead, zinc etc.) at different reaction conditions has to be investigated in order to improve the metal/slag reactions as well as the vaporization by selective oxidation in the anode furnace. Therefore, the thermodynamic conditions like reaction order and the activity coefficients at the copper refining process have to be known for the optimization of this technique. Additionally, the interaction between different elements has been investigated as a function of the temperature, the content of the elements, and the slag composition especially for nickel. These investigations were done at the Christian Doppler Laboratory for Secondary Metallurgy of Nonferrous Metals.
