In this session, Diana will describe how to create real-solution Pourbaix diagrams (or Potential vs pH diagrams) using OLI Studio. These real-solution Pourbaix diagrams generated with OLI software account for the activity coefficients of species in solution. Additionally, the OLI Pourbaix diagrams can be generated at different temperatures and pressures. These considerations create a more predictive diagram. Diana will present two different systems: (1) The Au-CN-H2O system to understand the gold cyanidation process for gold extraction, and (2) the effects of temperature and H2S concentration on the Fe-H2S-H2O system.
