Pyrite is a mineral containing 53.5% sulfur and 46.5% iron. Pyrite is mostly solid, finely granular, or globular. It is insoluble in water. Its name derives from fire, as it emits sparks when rubbed against other metals. It is also known as "fool's gold" or "poor man's gold" due to its strong resemblance.
