The mineral pyrite (/ ˈ p aɪ r aɪ t /), or iron pyrite, also known as fool''s gold, is an iron sulfide with the chemical formula FeS 2 (iron(II) disulfide). Pyrite is considered the most common form of sulfide minerals.. Pyrite''s metallic luster and pale brassyellow hue give it a superficial resemblance to gold, hence the wellknown nickname of fool''s color has also led to the

In various gold ores, the native gold commonly occurs as tiny particles contained within sulfide minerals such as pyrite. Iron pyrite is an exceedingly common associate with gold, but it also serves as a reducing agent. Therefore whenever gold is found encased in pyrite, it is always present as free gold and not as some type of gold sulphide.
