Pyrite | Common Minerals
Those iron oxide minerals occur in larger concentrations and volumes than pyrite, so they are a more economical iron source. Vein pyrite, however, may reveal the presence of other valuable minerals, such as chalcopyrite and gold. In the recent past, pyrite was mined as a sulfur source for sulfuric acid, an essential commodity for chemical industry.Web

How To Tell The Difference Between Pyrite And Gold
In terms of hardness, pyrite is relatively hard, ranking around 6 to 6.5 on the Mohs scale. This means that it can scratch glass, but not as easily as gold. Gold, on the other hand, is much softer and has a hardness of 2.5 to 3. This means that it can be easily scratched by a fingernail. Additionally, gold is quite dense and heavy, while pyrite ...Web
