Iron pyrite, also known as fool’s gold, is a common mineral found in sedimentary and metamorphic rocks. It is an iron sulfide with the formula FeS2. Pyrite is often mistaken for gold due to its metallic luster and brassy yellow color. However, pyrite is much less valuable than gold.
Value of Iron Pyrite
The value of iron pyrite is determined by its quality and quantity. High-quality pyrite crystals can be used in jewelry and other decorative applications. However, most pyrite is used as a source of sulfur in the production of sulfuric acid.
The price of pyrite fluctuates depending on the demand for sulfuric acid. In 2023, the average price of pyrite was $20 per ton. However, the price of pyrite is expected to increase in the coming years due to the growing demand for sulfuric acid.
