Dear Dr Parkhurst, PHREEQC2 offers exciting opportunity to conduct kinetic modelling. Working with tailings on gold mines and discard dumps on coal mines one of the problems encountered is pyrite oxidation. I'd like to gather some example files which deal with kinetic pyrite oxidation (in PHREEQC2) in two principal scenarios: - pyrite oxidation under unsaturated conditions with oxygen flow/diffusion (e.g. in discard heaps) - pyrite oxidation under flooding conditions of previoulsy mined space (i.e. what happens when a mine ceases its operation and is flooded) Would you happen to have some albeit fragmentary examples that I could develop into real-life simulations? Your advice or suggestions will be highly appreciated. Kind regards, Milo Simonic Hydromedia Solutions (Pty) Ltd Pretoria, South Africa
