Pyrite is not very commonly mined for obtaining iron, more often it is mined for its sulfur content. Pyrite is not mined for the iron possibly because it is not found in as large quantities as other iron ores such as [[hematite]] and [[magnetite]]. It is also not mined for the iron because the iron becomes brittle after being apart of iron pyrite and it therefore has no great purpose. Other than pure sulfur sources, pyrite is the major sulfur provider. During World War 2 sulfur was a needed chemical, and the mines containing sulfur, were running low, so Americans started using pyrite as a source of sulfur production. The sulfur collected from pyrite during this time, was used to create [[sulfuric acid]] which is important as an industrial used chemical.<ref name=pyrite/> Another reason pyrite is mined is because it may sometimes contain gold and therefore is mined for the gold content. Native Americans sometimes used pyrite as mirrors, they would take the pyrite and polish it, making it usable as a mirror. Even during modern times, pyrite may be used decoratively as an ornamental stone.<ref name=themineralpyrite/> The main uses for pyrite are producing sulfur dioxide and sulfuric acid. The sulfur dioxide made by pyrite is mostly used in the paper industry. While the sulfuric acid created from pyrite is used in the chemical industry. Now, pyrite is becoming less used because other substances that are easier accessed are replacing pyrite.<ref name=geology.com/> | Pyrite is not very commonly mined for obtaining iron, more often it is mined for its sulfur content.

Marcasite has the same chemical formula(FeS<sub>2</sub>) as pyrite. They are not considered the same mineral because they are classified into different crystal systems. SO even though marcasite may have the same elemental composition, it is different. The two minerals are often accidentally confused for one another. <ref name=themineralpyrite> [http://www.minerals.net/mineral/pyrite.aspx THE MINERAL PYRITE] ''The Mineral and Gemstone Kingdom''.
