Katelyn,
Thanks for the help! That makes sense, and now I know what speciate is doing. I updated the information, and now I'm getting pyrite as the dominant type of iron sulfide scale present. However, I know other scales can form, so I tried using the suppress feature. Is that a function of stability? So pyrite is the most stable, and the second most stable is pyrrhotite (see attached)?
Also, I looked through the mineral species, and the only iron sulfide compounds I saw were pyrrhotite, troilite, and pyrite. I am also aware of greigite, mackinawite, and marcasite. Is there a way to incorporate them as well?
Thank you!
