Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

The mineral pyrite, or iron pyrite, is iron sulfide, FeS 2.It has isometric crystals that usually appear as cubes. The cube faces may be striated (parallel lines on crystal surface or cleavage face) as a result of alternation of the cube and pyritohedron faces.

FeS2 is Pyrite structured and crystallizes in the cubic Pa-3 space group. The structure is three-dimensional. Fe3+ is bonded to six equivalent S+1.50- atoms to form corner-sharing FeS6 octahedra. The corner-sharing octahedral tilt angles are 64°. All Fe–S bond lengths are 2.25 Å. S+1.50- is bonded in a 3-coordinate geometry to three equivalent Fe3+ atoms.

During the thermal decomposition of pyrite, sulfur gas is released. Sulfur gas normally consists of a number of allotropic species [17], [18] and should be considered as a mixture rather than a pure gas. These allotropic species can be represented by S n, with n varying from 1 to 8 or higher. Under equilibrium conditions, the fraction of each species …

Pyrite has the chemical formula FeS2, meaning it is made up of one iron molecule, Fe, and two sulphur molecules, S. These then combine to form the cubic structure. This is a single pyrite crystal which you can see forms a perfect cube. A cube is not the only crystal shape that pyrite can form, however, and it can form many other crystal shapes ...

Pyrite, which sparks under percussion, provided portability (until the Iron Age). Mastery of fire happened perhaps hundreds of thousands or more years ago (the subject is controversial). It was the great instrument of change. Cooking plants and flesh rendered them safer and easier to digest, so a wider range of foods became available.
