A common mineral that consists of iron disulfide (FeS2), has a pale brass-yellow color and metallic luster, and is burned for the manufacture of sulfur dioxide and sulfuric acid
is an iron sulfide mineral, FeS2, more commonly known as "Fools Gold" In fresh samples, it is commonly found as striated cubes In sedimentary rocks, its presence is indicative of a reducing environment at the time of deposition
Iron sulfide mineral (FeS) Forms silvery to brassy metallic cubes or masses Common in many rocks Known as fool’s gold Weathered pyrite produces limonite (iron oxide) that stains rock brown or yellow
Sulphide of iron A common ore containing about 53% sulphur and 46 7% iron Commonly occurring in mineral deposits, its chief use is for the manufacture of sulphuric acid for which purpose it is roasted to obtain the sulphur as sulphur dioxide in the gaseous state
or iron pyrite or fool's gold Naturally occurring, gold-coloured iron disulfide mineral. Pyrite has frequently fooled prospectors into thinking they had discovered gold. Pure pyrite (FeS2) contains 47% iron and 53% sulfur, by weight. Pyrite is used commercially as a source of sulfur, particularly for the production of sulfuric acid. Because there are much better sources of iron, it is not generally used as an iron ore. For many years Spain was the largest producer; other countries include Japan, the U.S., Canada, Italy, Norway, Portugal, and Slovakia
