This is one of six different example models (all developed by Ted Eary of Enchemica) that illustrate how GoldSim can be used to carry out mixing and geochemical calculations. The models proceed from the simplest to the most complex. You can see an overview of all six models here.
This model provides an example of integrating chemical processes into a GoldSim model where the chemical processes are represented by theoretical equilibrium and empirical relationships developed by methods outside of GoldSim (in this case PHREEQC). The model simulates some of the major chemical processes that occur in a water treatment plant designed to neutralize and remove metals from an influent water typical of acid mine drainage. These processes require lime and air addition to the water and produce sludge.
