Arsenopyrite and chalcopyrite are not varieties of pyrite. Removed that and created arsenopyrite article.-- Vsmith 23:56, 19 Sep 2004 (UTC)
The melting point has been added to the data table. I'm not sure of the significance here and it probably needs to be qualified as it seems likely that, unless it is in a reducing environment, pyrite would oxidize and break down below that temperature if oxygen is present.

The article correctly states that pyrite comes from greek "pyr" meaning fire. It is interesting that the element Silica (Si) in greek is actually translated Pyrite. I was looking today at the chemical composition of Pyrite and i was searching in vain for silica!.-- User:Chris 3:02, 31 Aug 2005
In a 3 to 0 vote, this article has been delisted in a Good Article review.

Article: [2]
Is Pyrite a semiconductor?
Can anyone explain further how pyrite is used for PV cells when it is described earlier in the article that pyrite weathers away over time? —Preceding unsigned comment added by 24.196.150.8 ( talk) 23:50, 10 June 2009 (UTC)
" Auriferous pyrite is a valuable ore of gold." I removed this from intro. It literally says, "gold bearing pyrite is mined for gold." —Preceding unsigned comment added by 203.38.62.211 ( talk) 05:47, 5 December 2010 (UTC)
I reverted the section on taphonomy because the Alaska fossil preserved in--among other things--pyrite crystals is interesting but not notable. While a case may certainly be made for giving the Hadrosaur its own page, to include it here would seem to mean it would have to be included in the pages on Sand, Mud and Ocean Water. It's not like it was found encased in a solid-pyrite geode-like structure, at least not the way I read the cited text. Anyone have any thoughts? — UncleBubba ( T @ C ) 03:19, 5 April 2011 (UTC)
Am I crazy, or is there no place to read or talk about the formation of pyrite? Um, like how it can only be formed in oxygen free environments and tends to be a framboid on other rocks? Does the formation section really not exist? — Preceding unsigned comment added by KreebleFlarg ( talk • contribs) 06:44, 16 April 2011 (UTC)
Although one may well start out with CaF2 as a decription and then move the sulfur atoms away from ideal fluorite positions, this is hardly a helpful way of arriving at structural understanding because the shift has be rather large, resulting in a distance between the sulfur atoms clearly that becomes a bonding distance. In the fluorite there is no F-F bonding distance. Failing to point that out creates an odd contradiction-by-omission with the previous topic.
Another important point that is not made in the story is that the iron atom is not only a Fe(II) species but that it is in a low spin state Fe(II) species, giving the material a diamagnetic character. This can be understood from the (distorted) octahedral coordination of the iron by the disulfide (persulfide if you wish) moeities a strong ligands, not if you keep thinking in terms of loose sulfur atoms. Neither the octahedral coordination nor the spin state are mentioned and the structural description is rather garbled therefore. Jcwf ( talk) 02:51, 9 June 2011 (UTC)
The page for chemical salts links to this page, reffering to it as a type of salt.
Shouldn't this be mentioned in this article? 69.132.69.87 ( talk) 19:46, 16 December 2011 (UTC)
I have added a section "Pyrite in building structures" to this article. I understand that this new section is not about geology or minerals and that the article is directed toward the chemical aspect of Pyrite. However some users may be searching for information about structural defects caused by pyrite when reading this article but such information were not included. I believe that the new section is a complement on this particular subject which is not covered by any other article on Wikipedia.-- Christophe Krief ( talk) 18:45, 15 February 2012 (UTC)

Pyrite, or iron pyrite, is an iron sulfide with the chemical formula FeS2. It is the most abundant sulfide mineral. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, and the mineral is known informally as "fool's gold". The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal. Pyrite is usually found associated with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic rock, as well as in coal beds and as a replacement mineral in fossils, but has also been identified in the sclerites of scaly-foot gastropods. It has had various uses over time, including as an ignition for firearms, a source of sulfur dioxide and as jewellery. These cubic crystals of pyrite were found in the Huanzala mine in the Huallanca District of Peru. Photograph credit: Ivar Leidus
