I was wondering if anyone has some experience regarding my question. The geochemical simulation of mixing a mole of pyrite with a kilogram of acidic solution (pH=1) shows that Pyrite almost remains intact (PHREEQC). Do lab observations confirm this?

I would expect it to react. – Ivan Neretin Mar 13 '21 at 01:07

I would expect it to react, especially if there is oxygen (e.g. from the atmosphere) present, even in small amounts. Not sure if PHREEQC assumes this. – Curt F. Mar 13 '21 at 06:07
