| Abstract: | Thermodynamic equilibrium of Cu-Ni-Cl-H2O system as nickel anolyte was calculated according to the thermodynamic data available.The equilibrium constants of the ions such as Cu2+,Ni2+,and coordination complexes in this system were calculated at pH=2.5 and the lg c(Me) vs c(Cl)T diagrams of concentration relationship in this system were drawn at 298.15 K.The investigation result showed that the copper concentration in this system could be decreased to 3 mg/L by replacement deposition method and the mass ratio of copper to nickel greater than 20 in the slag,so that the requirement of nickel electrorefining was met. |
