[OLD] Plotting of siderite on fO2-pH diagrams - Act2 ...

26-12-2004· From: Garry Davidson Subject: Plotting of siderite on fO2-pH diagrams We've recently had a controversy over whether GWB plots siderite correctly on fO2-pH diagrams...it appears that GWB can only consider the S species, or only the C-species, and not both S and C, for one diagram, but siderite req...

Eh-pH Diagrams

Eh-pH diagrams (aka Pourbaix diagrams, electrochemical phase diagrams) are important to the development of hydrometallurgical and electrometallurgical processes. The diagrams present a roadmap to processes that separate one metal from another in an ore or concentrate, precipitate compounds from solution, purify wastewater, and generate metal by electrolytic processes.
