ruth Posted October 1, 2009 Share Posted October 1, 2009 Hello, We are trying to reproduce the diagram Eh vs pH for the system Cu-O-H-S under different concentrations of Cl- using the Act2 program (v 6.0). Our problem is when we include the covellite and chalcocite to the diagram, the field of the soluble chemical species of Cu (Cu2+ and CuCl-2) and the minerals (tenorite, curpite and native copper) disappear. We attachement the pdf article. The figure that we can reproduce is fig. 2 Thank your for your help Ruth p1036-p1048.pdf Link to comment Share on other sites More sharing options...

The figure that we can reproduce is fig. 2 Thank your for your help Ruth Hi Ruth: The attached script mostly resembles figure 2, other than that the default thermo database is missing data for anilite, djurlite and Cu4(OH)6Cl2. Re-creating the diagram is one thing, but understanding the assumptions behind it are another, so feel free to ask me questions about this configuration. Regards, Tom Meuzelaar RockWare, Inc.
