Pyrite is a brass-yellow mineral with a bright metallic luster. It has a chemical composition of iron disulfide (FeS 2) and is the most common sulfide mineral. It forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic and sedimentary rocks worldwide.
It is not iron(IV) sulfide; the iron is in a +2 oxidation state, combined with an S 2 2- ion (the sulfur analog of the peroxide ion). Pyrite burns when heated to form sulfur dioxide and iron(III) oxide: The reaction is sometimes used in industry as a source of sulfur dioxide for the manufacture of sulfuric acid.he same pigment can be obtained from the reaction of iron(II) with ferricyanide: The product of the reaction is the blue color ingredient in many artist's pigments, printing inks, and dyes (including Berlin blue, Chinese blue, mineral blue, Paris blue, and Prussian blue).
