 · Pyrite is common along the borders of Minnesota, Iowa and Wisconsin, in the northern part of the Upper Mississippi River Valley lead-zinc mining district. There it occurs as vein deposits and as a disseminated replacement mineral in the region's widespread Paleozoic carbonate rock layers.

 · The pyrite from coal mining in southern Santa Catarina (Brazil) is rich in other ferrous compounds, sulfates and oxides according to the infrared spectra. The high silicon content, together with elements such as aluminum, calcium, potassium, magnesium, manganese and sodium, suggest that the material has a sandy and clay fraction.

Pyrite is sometimes called Fools Gold because of its similarity in color and shape to Gold.In the old mining days, Pyrite was sometimes mistaken for Gold, as they frequently occur together, although Gold and Pyrite can very easily be distinguished by simple observation and testing of …

0.62% of all Copper deposits have Iron pyrite. 43.10% of all Iron pyrite deposits have Copper. 0.60% of all Lead deposits have Iron pyrite. 34.48% of all Iron pyrite deposits have Lead. 0.86% of all Zinc deposits have Iron pyrite. 31.61% of all Iron pyrite deposits have Zinc. 0.42% of all Silver deposits have Iron pyrite.

 · Pyrite oxidation, which can lead to acid mine drainage, is a concern for miners all across the globe. However, little is known about the processes that cause this phenomenon.

 · The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).
