Uses
Pyrite is used to create iron sulfate that is used to make nutritional supplements, ink, lawn conditioner, water treatment and flocculation, moss killer, and many other chemical processes. Iron sulfate which comes from pyrite is used to treat iron-deficiency anemia. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.
