Hi! I was just wondering if the decomposition of ferric sulfide can break down into S8 molecules and ferric ions? Thanks in advance!!

I think the oxidative decomposition of $$FeS$$ will only produce $$Fe_2O_3$$ and $$SO_2$$ or $$SO_3$$, depending on the oxygen concentration. If it is sufficiently low, then a very slow conversion of $$Fe_2S_3$$ to $$Fe_2O_3$$ and elemental sulfur, which oligomerizes into $$S_8$$ rings, might be possible.
