Symposium PbZn 2020: The 9th International Symposium on Lead and Zinc Processing
Presentation Title The removal of arsenic from lead bullion via vacuum distillation

Abstract Scope Metal refining under reduced pressure has been recognized as a more environmentally friendly process. Because arsenic sublimates at 1 atm, a lack of thermodynamic data for As-X binary systems paused a challenge for the extensive study of arsenic removal from lead bullion. Physico-chemical properties of liquid arsenic were obtained to calculate the activity coefficients of As and Pb necessary for the calculation of vapor-liquid equilibrium (VLE) between 5 and 20 Pa for the binary Pb-As system to predict the required distillation temperature. Laboratory experiments were conducted in the time, temperature and pressure ranges of 30-60, 550-650, and 5-20 respectively to investigate their effect on arsenic removal from lead. Results showed that the extent of arsenic removal increased with an increase in time while the arsenic content in the distillate fraction decreased with longer distillation time. It was also observed that arsenic content decreased with an increase in temperature and pressure.
