Pyrite is used with flintstone and a form of tinder made of stringybark by the Kaurna people of South Australia, as a traditional method of starting fires. [17] Pyrite has been used since classical times to manufacture copperas (ferrous sulfate). Iron pyrite was heaped up and allowed to weather (an example of an early form of heap leaching ...
There are indications that the Iceman, also known as Ötzi, may have used iron pyrite to make fire. [5] From the Iron Age forward, until the invention of the friction match in the early 1800s by John Walker, the use of flint and steel was a common method of fire lighting.
Copperas house, Limb Valley. Copperas (iron(II) sulfate) was manufactured here from the pyritic Ringinglow coal seam, mined nearby. The copperas solution was used in the leather tanning industry. Copperas works are manufactories where copperas (iron(II) sulfate) is produced from pyrite, often obtained as a byproduct during coal mining, and iron
Similarly, two pieces of iron pyrite or marcasite when struck together can create sparks. The use of flint in particular became the most common method of producing flames in pre-industrial societies (see also fire striker).

Pyrrhotite (pyrrhos in Greek meaning "flame-coloured") is an iron sulfide mineral with the formula Fe (1-x) S (x = 0 to 0.125). It is a nonstoichiometric variant of FeS, the mineral known as troilite. Pyrrhotite is also called magnetic pyrite, because the color is similar to pyrite and it is
