Pyrite, also known as fool's gold, is a common mineral with a yellow-silver colour and metallic luster. It is composed of iron and sulfur and has a chemical formula of FeS2. Pyrite is found in many types of rock, including sedimentary, metamorphic, and igneous, and is often associated with other minerals such as quartz and calcite. Pyrite is a hard and brittle mineral that is resistant to weathering and is often found in the form of cubic or pyritohedral crystals. The name "pyrite" comes from the Greek word "pyr," which means "fire," because it was once used as a source of ignition for fire. Pyrite has a variety of uses, including as a source of sulfur, in the production of sulfuric acid, and as a decorative mineral. It is also used in the production of iron and steel, and has been mined for centuries as a source of iron.
