But I wondered that if the phreeqc database include schwertmannite ,if not,what kind data should I add to it? The PHREEQC data bases do not include schwertmannite. If you know a chemical reaction and an equilibrium constant, you can add a new mineral with the PHASES data block. You may be able to find this information in the geochemical literature. If you find the information, I would like to see it or the references. Jarosite and Fe(OH)3(a) or Goethite are other minerals with similar stability that will give you an idea of the mineral reactions in mine waters.
