Pyrite - Wikipedia
Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold.The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.. The name pyrite is derived from the Greek πυρίτης λίθος (pyritēs lithos), "stone or mineral which strikes fire", in turn from ...

4 Extraction Processes for Gold-Pyrite Ore
Pyrite was once a source of sulfur and sulfuric acid, but today most sulfur is obtained as a byproduct of natural gas and crude oil processing. Today pyrite is sometimes sold as a novelty item or costume jewelry. But pyrite isn't entirely useless; in fact it's a good way to find real gold because the two form together under similar conditions.

Pyrite - Wikipedia
This process is accelerated by the action of Acidithiobacillus bacteria which oxidize pyrite to first produce ferrous ions ( Fe2+ ), sulfate ions ( SO2− 4 ), and release protons ( H +, or H3O+ ). In a second step, the ferrous ions ( Fe2+ ) are oxidized by O 2 into ferric ions ( Fe3+ ) which hydrolyze also releasing H + ions and producing FeO (OH).
