I am trying to simulate water quality of runoff and seepage from a waste rock dump.
I currently have the mineralogy from XRD analysis and trace element concentrations of waste rock.
I would like to determine the chemistry resulting from the interaction of rain with for example; Rhyodacite or Andesite.
I have entered the Basis solution along with the kinetic reactants (minerals present as per XRD results) however would like to know how to incorporate additional trace elements.
For example the mineral phases present include;
Quartz
Anorthite
Calcite
Anatase
Pyrite
Kaolinite
Montmorillonite.
How can I include trace quanities of As, Pb, Ni, V ect?
Thank you for your help
