· Introduction. Pyrite, a mineral with a chemical formula of FeS 2, is an iron disulfide, which is usually associated with other sulfides and oxides. It is abundant in the earth's surface, being found in the composition of sedimentary and metamorphic rocks, in coal beds and as a replacement mineral in fossils (Klein and Hurlbut, 1993).
