Abstract Phase equilibrium and thermodynamic experimental data in the Cu 2O - SiO2, Cu2O - CaO, and Cu2O - CaO - SiO2 systems in equilibrium with metallic copper have been critically reviewed. The Modified Quasichemical and Bragg-Williams models in the FactSage computer package were used to describe the Gibbs energy of the molten slag phase as a function of composition and temperature. The available data have been used to optimize simultaneously a set of parameters in thermodynamic model equations for the Gibbs energy of liquid slag. The present thermodynamic optimization was carried out as part of the development of a thermodynamic database of copper-containing slag systems.
