| Abstract: | During tungsten extraction,the solution showed extraordinarily high copper concentration after the molybdenum was removed by selective precipitation process.Aiming at this phenomenon,thermodynamic calculation for the complex equilibrium system of Cu-NH3-Cl-S was carried out according to the simultaneous equilibrium principle,and the related equilibrium diagrams were also drawn.The results indicated that,copper could form various complex ions with HS-,NH3,Cl-,OH-and other anions.But most of them had quite lo... |
