[Raffinate Solution X2t Model]

Melika,

Thank you for the response. You are correct in that several of these minerals would not be stable in the system but we are anticipating rapid dissolution. I have since edited the mineral composition (removed anorthite and magnetite for simplicity) and adjusted the partial pressure of oxygen in the model (which  was not set correctly).

The Inlet fluid (groundwater) was sampled on site and analyzed by a commercial lab. The raffinate chemistry was provided by the manufacturer. Both solutions have been balanced using specE8. The model appears to be having trouble with the initial basis. Should mineral volumes be part of the reactants pane instead of the initial basis? Thank you.

[Raffinate Solution X2t Model]

Hello,

I am attempting to model an in-situ leaching process with X2t. Sulfate concentrations in the raffinate solution are quite high and the model is having trouble converging, producing the error:

Solving for initial state of each nodal block.
Residuals too large, 689-th interation

Any suggestions as to why specifically the model is having trouble? Thank you!

Does a report command exist for "Cumulative mass influxes and effluxes over simulation" ?

Thank you.
