اقرأ أكثرThere are three different mechanisms that occur to produce pyrite. One involves iron (II) and polysulfide, the other uses FeS and S (-II), and the last is growth of pyrite crystal growth on pyrite seeds [ 31 − 35 ]. It is important to note that the first two of these reactions involve an [FeS] intermediate step.
