Abstract
Based on thermodynamic calculation results of Fe-Cu-Cl-O system by FACTSAGE software, chlorinate reaction of Fe-Cu-O melts was studied. The (CuCl)3(g) gas can stably exist under a certain condition. At 1273K, the high purity N2gas was used as the carrier gas to decrease the partial pressure of (CuCl)3(g) gas of FeO-Cu2O-CaCl2melt to promote the generation of of (CuCl)3(g). Thus Cu was transformed to chlorides and removed from the melt. Between 1123K and 1273K, after specimen of FeO-Cu2O-CaCl2system was sintered for 4h, the evaporation ratios of Cu and Fe were 55.45 % and 4.02 %, respectively. The results show that the chlorination reaction is an effective method to recycle the copper and iron.
