At present, copper smelting slag is not effectively recycled and is wasted. Copper smelting slag contains FexO at more than 40 mass%. For the utilization of copper slag as a Fe resource, it is necessary to separate the Cu in the slag. For copper recycling from slag, FeS-based matte can be introduced to use sulfurization to concentrate Cu from the slag into the sulfide and finally recover the copper. In a previous paper, a kinetic model was developed to simulate the coupled reactions between the multicomponent slag and FeS-based matte by using previously reported thermodynamic data. Building on this work, we carried out equilibrium experiments to supplement the thermodynamic data used in the previously developed model. An empirical formula for the Cu2O activity coefficient of Cu2O-FeOX-CaO-MgO-SiO2-Al2O3 system slag was obtained. In addition, the effect of alumina content in the slag on the Cu2O activity coefficient in the slag was investigated. The model was also supplemented to account for MgO solubility. By the developed model and the industrial conditions, we investigated the effect of slag composition on the behavior of Cu between matte and Cu2O-FeOX-CaO-MgO-SiO2-Al2O3 system slag for the copper loss.
