Estimation And Thermodynamic Modeling Of Solid Iron Species In The Berkeley Pit Water, Rajesh Srivastava
Estimation And Thermodynamic Modeling Of Solid Iron Species In The Berkeley Pit Water, Rajesh Srivastava
Graduate Theses & Non-Theses
Since the cessation of open-pit mining activities from the Berkeley Pit located in Butte, MT in 1982, the pit had gradually filled with metal-laden acidic mine water. The purpose of this investigation was to estimate and apply thermodynamic theory to a group of iron-sulfate solids that might equilibrate with the Berkeley Pit water. Thermodynamic data was incomplete for acid mine affected water, and the effects of Cu cementation on the formation of iron oxide and sulfate solids had not been analyzed. Ferric iron compounds such as Ferrihydrite, Goethite, Schwertmannite, Potassium Jarosite and Potassium Hydronium Jarosite were modelled in Stabcal using …
