Solvent extraction equilibria in the CuSO4-H2SO4-H2O-LIX 860-kerosene system
The equilibrium isotherm and distribution coefficients were determined for the CuSO4-H2SO4-H2O-LIX 860-kerosene solvent extraction system at 25 degrees C and aqueous copper concentrations below 500 mg/L. A previously developed thermodynamic model for extraction equilibria closely predicted the experimentally measured distribution coefficients.
