Abstract

For the application of Na2CO3 slag to the elimination of iron from molten copper, the thermodynamic properties of the Cu-O-Fe system and the distribution behavior of iron between the NaO0.5-CO2-FeO1.5 slag and molten copper have been studied. The first order interaction parameter in molten copper was determined by the equilibrium distribution experiments between the NaFeO2-saturated slag and molten copper. The lower CO2 partial pressure and the higher oxygen partial pressure are more preferable for the removal of iron from molten copper.
