It is essential to efficiently remove sulfur from complex copper concentrates to enable effective smelting via carbon reduction, especially as these concentrates are increasingly complex and low grade. This study aims to investigate the kinetics of the oxidation process in complex copper concentrates using a thermogravimetric method across a temperature range of 998 to 1073 K and an oxygen partial pressure range of 15.20 to 50.66 kPa. The results reveal a rapid oxidation rate throughout the entire temperature spectrum, with approximately 95% of the sulfur being eliminated after merely 15 minutes at 1073 K with an oxygen partial pressure of 21.28 kPa. The sulfur removal over time was analyzed utilizing a shrinking-core model, clarifying the significant influence of oxygen partial pressure on the oxidation rate. These findings contribute valuable insights towards enhancing the carbon reduction process for the efficient processing of complex copper concentrates, thereby supporting the sustainability of copper smelting operations.
