| Abstract |
This study was undertaken to investigate the distribution ratio of silver between metals and slags during lead slime smelting processes. The antimony activities of the lipuid Sb-Pb-Ag system at 1250K were determined by using isothermal and isopiestic equilibrium methods. At 1250K, the equilibrium distributions between the Sb₂O₃ PbO slag and Sb-Pb-Ag metal, and Sb-Pb-Bi-Ag metal were studied. The results are summarized as follows;l) The activities of Sb in liquid Sb-Pb-Ag system at 1250K showed a slight negative deviation from Raoult`s law at low Sb concentrations and obeyed Raoult`s law at high Sb concentrations. 2) Liquid Sb-Pb-Ag system presents the behaviors of regular solution in a minute error. 3) Difference between the behaviors of silver and other elements during lead slime smelting processes was also discussed based on the thermodynamic data obtained in present investigations. |
