Title: Reactions of iron monosulfide solids with aqueous hydrogen sulfide up to 160°C
Abstract: Reactions of powdered samples of the iron monosulfide phases mackinawite (tetragonal FeS1−x troilite (hexagonal FeS) and a hexagonal pyrrhotite (Fe0.9S), and of single crystals of troilite, with aqueous H2S at a total pressure of 1.8 MPa and temperatures up to 160°C have been investigated. The reaction sequences mackinawite → (greigite) → pyrrhotite → pyrite, and troilite → pyrrhotite → pyrite have been established by X-ray powder diffractometry. Morphological examination by scanning electron microscopy has permitted a distinction to be made between solid state and solution pathways for most of the transformations and factors which affect the rate of crystallization of pyrite have been identified.
