Iron Pyrite (Pyrite), often known as “Fool’s Gold,” is a naturally occurring iron sulfide mineral valued for its distinctive metallic luster and rich iron content. Found in sedimentary, metamorphic, and hydrothermal geological formations worldwide, pyrite is one of the most abundant sulfide minerals on Earth. For industrial and ingredient applications, iron pyrite serves as a reliable source of iron and is used across a range of manufacturing, processing, and specialty product formulations.
